Doctor - Physician
or physician is a professional
who practices medicine, which is concerned with promoting, maintaining, or
restoring health through the study, diagnosis, and treatment of disease,
injury, and other physical and mental impairments. Physicians may focus
their practice on certain disease categories, types of patients and
methods of treatment—known as specialties—or they may assume
responsibility for the provision of continuing and comprehensive medical
care to individuals, families, and communities—known as general practice.
Medical practice properly requires both a detailed knowledge of the
academic disciplines (such as anatomy and physiology) underlying diseases
and their treatment—the science of medicine—and also a decent competence
in its applied practice—the art or craft of medicine.

is language used to
precisely describe the human body including its components, processes,
conditions affecting it, and procedures performed upon in. It is to be
used in the field of medicine. Notable aspects of medical terminology
include the use of Latin terms and regular morphology, with the same
suffixes and prefixes use quite consistently for a particular meaning.
This regular morphology means that once reasonable number of morphemes are
learned it becomes easy to understand very precise terms build up from
these morphemes. A lot of medical language is anatomical terminology,
concerning itself with the names of various parts of the body.

is a doctor who performs
operations, which is a medical procedure involving an incision with
instruments; performed to repair damage or arrest disease in a living
body. Incision is cutting of or into body tissues or organs. Surgeons may
be physicians, podiatrists, dentists, or veterinarians.
Color Coded Surgery
refers to surgical techniques
that limit the size of incisions needed and so lessens wound healing time,
associated pain and risk of infection. An endovascular aneurysm repair as
an example of minimally invasive surgery is much less invasive in that it
involves much smaller incisions, than the corresponding open surgery
procedure of open aortic surgery.

is a medical
procedure in which an organ is removed from one body and placed in the
body of a recipient, to replace a damaged or missing organ. The donor and
recipient may be at the same location, or organs may be transported from a
donor site to another location. Organs and/or tissues that are
transplanted within the same person's body are called autografts.
Transplants that are recently performed between two subjects of the same
species are called allografts. Allografts can either be from a living or
is when a person allows
to be removed, legally, either by consent while the donor is alive or
after death with the assent of the next of kin. Donation may be for
research, or, more commonly healthy transplantable organs and tissues may
be donated to be transplanted into another person. Common transplantations
include: kidneys, heart, liver, pancreas, intestines, lungs, bones, bone
marrow, skin, and corneas. Some organs and tissues can be donated by
living donors, such as a kidney or part of the liver, but most donations
occur after the donor has died. As of August 1, 2016, there are 120,004
people waiting for life-saving organ transplants in the US. Of these,
96,645 await kidney transplants. While views of organ donation are
positive there is a large gap between the numbers of registered donors
compared to those awaiting organ donations on a global level.

Whether the patient is available (for example, whether the patient can be
contacted and has no current infection or other temporary reason that
transplant cannot take place). Depending on the organ, however, some
factors become more important. For example, some organs can survive
outside the body longer than others. So the distance between the donor's
hospital and the potential recipient's hospital must be taken into
consideration.Can an organ recipient
choose an organ from a younger person?
Putting a kidney from a 70
year old donor into a 20 year old recipient is not a great idea. In the
reverse situation a 20 year old kidney transplanted into a 70 year old
will be exposed to an aging environment: high blood pressure, other organs
which are not functioning optimally and it will not last as long as it
would in a 20 year old recipient (assuming the etiology is not prone to
recurrence). A 70 year old kidney would probably last longer in a
year old than in another 70 year old but sometimes young and otherwise
healthy patients have a greater tendency to reject than older ones. In any
case, some sort of age matching makes sense if feasible. The biological
age of the transplanted organ won't change after it has been transplanted.

in the brain that are characterized by their extensive vasculature and
lack of a normal blood brain barrier
The CVOs allow for the linkage between the central nervous system and
peripheral blood flow; additionally they are an integral part of
neuroendocrine function. The lack of a blood brain barrier allows the CVOs
to act as an alternative route for peptides and hormones in the neural
tissue to the peripheral blood stream, while still protecting it from
toxic substances. CVOs can be classified as either sensory or secretory
organs. The sensory organs include the area postrema (AP), the subfornical
organ (SFO) and the vascular organ of lamina terminalis. They have the
ability to sense plasma molecules and then pass that information into
other regions of the brain. Through this, they provide direct information
to the autonomic nervous system from the systemic circulation. The
secretory organs include the subcommissural organ (SCO), the posterior
pituitary, the pineal gland, the median eminence and the intermediate lobe
of the pituitary gland. These organs are responsible for secreting
hormones and glycoproteins into the peripheral vascular system using
feedback from both the brain environment and external stimuli. All of the
circumventricular organs, besides the SCO, contain extensive vasculature
and fenestrated capillaries which leads to a ‘leaky’ BBB at the site of
the organs. Furthermore, all CVOs contain neural tissue, allowing them to
play a role in the neuroendocrine system. It is highly debated if the
choroid plexus can be included as a CVO. It has a high concentration of
fenestrated capillaries, but its lack of neural tissue and its primary
role of producing cerebrospinal fluid (CSF) usually excludes the choroid
plexus from the CVO classification. Research has also linked CVOs to body
fluid regulation, cardiovascular functions, immune responses, thirst,
feeding behavior and reproductive behavior

The Human Body
is the entire structure
of a human being. It is composed of many different types of cells that
together create tissues and subsequently organ systems. They ensure
homeostasis and viability of human body. It comprises a head, neck, trunk
(which includes the thorax and abdomen), arms and hands, legs and feet.
The study of the human body involves anatomy, physiology, histology and
embryology. The body varies anatomically in known ways. Physiology focuses
on the systems
of the human body and their functions. Many
systems and mechanisms interact in order to maintain
safe levels of substances such as sugar and oxygen in the blood. The body
is studied by health professionals, physiologists, anatomists, and by
artists to assist them in their work.

is the branch
of biology concerned with the study of the structure of organisms and
their parts. Anatomy is inherently tied to embryology, comparative
anatomy, evolutionary biology, and phylogeny, as these are the processes
by which anatomy is generated over immediate (embryology) and long
(evolution) timescales. Human anatomy is one of the basic essential
sciences of medicine. The discipline of anatomy is divided into
macroscopic and microscopic anatomy. Macroscopic anatomy, or gross
anatomy, is the examination of an animal's body parts using unaided
eyesight. Gross anatomy also includes the branch of superficial anatomy.
Microscopic anatomy involves the use of optical instruments in the study
of the tissues of various structures, known as histology, and also in the
study of cells. The history of anatomy is characterized by a progressive
understanding of the functions of the organs and structures of the human
body. Methods have also improved dramatically, advancing from the
examination of animals by dissection of carcasses and cadavers (corpses)
to 20th century medical imaging techniques including X-ray, ultrasound,
and magnetic resonance imaging. Anatomy and physiology, which study
(respectively) the structure and function of organisms and their parts,
make a natural pair of related disciplines, and they are often studied

is a narrow
range indicating optimal health and thermoregulation. Individual body
temperature depends upon the age, exertion, infection, sex, time of day,
and reproductive status of the subject, the place in the body at which the
measurement is made, the subject's state of consciousness (waking or
sleeping), activity level, and emotional state. Despite these factors,
typical values are well established: oral (under the tongue): 36.8±0.4 °C
(98.2±0.72 °F), internal (rectal, vaginal): 37.0 °C (98.6 °F).
is the ability of an organism to keep its body temperature within certain
boundaries, even when the surrounding temperature is very different. A
thermoconforming organism, by contrast, simply adopts the surrounding
temperature as its own body temperature, thus avoiding the need for
internal thermoregulation. The internal thermoregulation process is one
aspect of homeostasis: a state of dynamic stability in an organism's
internal conditions, maintained far from thermal equilibrium with its
environment (the study of such processes in zoology has been called
physiological ecology). If the body is unable to maintain a normal
temperature and it increases significantly above normal, a condition known
as hyperthermia occurs. For humans, this occurs when the body is exposed
to constant temperatures of approximately 55 °C (131 °F), and with
prolonged exposure (longer than a few hours) at this temperature and up to
around 75 °C (167 °F) death is almost inevitable. Humans
may also experience lethal hyperthermia when the wet bulb temperature is
sustained above 35 °C (95 °F) for six hours. The opposite condition, when
body temperature decreases below normal levels, is known as hypothermia.
Temperature Sensors List
is the sense by which an organism perceives temperatures. The details of
how temperature receptors work are still being investigated. Ciliopathy is
associated with decreased ability to sense heat, thus cilia may aid in the
process. Transient receptor potential channels (TRP channels) are
believed to play a role in many species in sensation of hot, cold, and
pain. Mammals have at least two types of sensor: those that detect heat
(i.e., temperatures above body temperature) and those that detect cold
(i.e. temperatures below body temperature.
, also called an
infrared camera or thermal imaging camera, is a device that forms an image
using infrared radiation, similar to a common camera that forms an image
using visible light. Instead of the 400–700 nanometre range of the visible
light camera, infrared cameras operate in wavelengths as long as 14,000 nm
(14 µm). Their use is called thermography.
is thermoregulation that maintains a stable
internal body temperature regardless of external influence. This internal
body temperature is often, though not necessarily, higher than the
animal species can maintain a body temperature higher than their
environment. In particular, homeothermic species maintain a stable body
temperature by regulating metabolic processes. The only known homeotherms
are birds and mammals. Other species have various degrees of
is an organism that maintains
its body at a metabolically favorable temperature, largely by the use of
heat set free by its internal bodily functions instead of relying almost
purely on ambient heat. Such internally generated heat is mainly an
incidental product of the animal's routine metabolism, but under
conditions of excessive cold or low activity an endotherm might apply
special mechanisms adapted specifically to heat production. Examples
include special-function muscular exertion such as shivering, and
uncoupled oxidative metabolism such as within brown adipose tissue. Only
birds and mammals are extant universally endothermic groups of animals.
Certain lamnid sharks, tuna and billfishes are also endothermic.In common
parlance, endotherms are characterized as "warm-blooded". The opposite of
endothermy is ectothermy, although there is no absolute or clear
separation between the nature of endotherms and ectotherms in general.
is the narrowing of the blood vessels
resulting from contraction of the muscular wall of the vessels, in
particular the large arteries and small arterioles. The process is the
opposite of vasodilation, the widening of blood vessels. The process is
particularly important in staunching hemorrhage and acute blood loss. When
blood vessels constrict, the flow of blood is restricted or decreased,
thus retaining body heat or increasing vascular resistance. This makes the
skin turn paler because less blood reaches the surface, reducing the
radiation of heat. On a larger level, vasoconstriction is one mechanism by
which the body regulates and maintains mean arterial pressure.
is an organism whose internal temperature
varies considerably. It is the opposite of a homeotherm, an organism which
maintains thermal homeostasis. Usually the variation is a consequence of
variation in the ambient environmental temperature. Many terrestrial
ectotherms are poikilothermic. However some ectotherms remain in
temperature-constant environments to the point that they are actually able
to maintain a constant internal temperature (i.e. are homeothermic). It is
this distinction that often makes the term "poikilotherm" more useful than
the vernacular "cold-blooded", which is sometimes used to refer to
ectotherms more generally. Poikilothermic animals include types of
vertebrate animals, specifically fish, amphibians, and reptiles, as well
as a large number of invertebrate animals. The naked mole-rat is the only
mammal that is currently thought to be poikilothermic.
is a group of disorders caused by dysfunctional mitochondria, the
organelles that generate energy for the cell. Mitochondria are found in
every cell of the human body except red blood cells, and convert the
energy of food molecules into the ATP that powers most cell functions.
is a common disorder of
the endocrine system in which the thyroid gland does not produce enough
thyroid hormone. It can cause a number of symptoms, such as poor ability

neck due to goitre. Untreated hypothyroidism during pregnancy can lead to
delays in growth and intellectual development in the baby, which is called
refers to organisms with a high active
metabolism and a considerably slower resting metabolism. Bradymetabolic
animals can often undergo dramatic changes in metabolic speed, according
to food availability and temperature. Many bradymetabolic creatures in
deserts and in areas that experience extreme winters are capable of
"shutting down" their metabolisms to approach near-death states, until
favorable conditions return (see hibernation and estivation).
Targeted Temperature Management
previously known as therapeutic hypothermia or protective hypothermia is
active treatment that tries to achieve and maintain a specific body
temperature in a person for a specific duration of time in an effort to
improve health outcomes during recovery after a period of stopped blood
flow to the brain. This is done in an attempt to reduce the risk of tissue
injury following lack of blood flow. Periods of poor blood flow may be due
to cardiac arrest or the blockage of an artery by a clot as in the case of
a stroke. Targeted temperature management improves survival and brain
function following resuscitation from cardiac arrest. Evidence supports
its use following certain types of cardiac arrest in which an individual
does not regain consciousness. Both 33 °C (91 °F) and 36 °C (97 °F) appear
to result in similar outcomes. Targeted temperature management following
traumatic brain injury has shown mixed results with some studies showing
benefits in survival and brain function while others show no clear
benefit. While associated with some complications, these are generally
mild. Targeted temperature management is thought to prevent brain injury
by several methods including decreasing the brain's oxygen demand,
reducing the production of neurotransmitters like glutamate, as well as
reducing free radicals that might damage the brain. The lowering of body
temperature may be accomplished by many means including the use of cooling
blankets, cooling helmets, cooling catheters, ice packs and ice water
is elevated body
temperature due to failed thermoregulation that occurs when a body
produces or absorbs more heat than it dissipates. Extreme temperature
elevation then becomes a medical emergency requiring immediate treatment
to prevent disability or death. The most common causes include heat stroke
and adverse reactions to drugs. The former is an acute temperature
elevation caused by exposure to excessive heat, or combination of heat and
humidity, that overwhelms the heat-regulating mechanisms. The latter is a
relatively rare side effect of many drugs, particularly those that affect
the central nervous system. Malignant hyperthermia is a rare complication
of some types of general anesthesia. Hyperthermia differs from fever in
that the body's temperature set point remains unchanged. The opposite is
hypothermia, which occurs when the temperature drops below that required
to maintain normal metabolism. The term is from Greek υπε, ype, meaning
"excess", and θερμία, thermía, meaning "heat".
, defined as hyperthermia with a body temperature greater than
40.6 °C (105.1 °F) because of environmental heat exposure with lack of
thermoregulation. This is distinct from a fever, where there is a
physiological increase in the temperature set point of the body. The term
"stroke" in "heat stroke" is a misnomer in that it does not involve a
blockage or hemorrhage of blood flow to the brain. Preventive measures
include drinking plenty of cool liquids and avoiding excessive heat and
humidity, especially in unventilated spaces, such as parked cars, that can
overheat quickly. Treatment requires rapid physical cooling of the body.
is reduced body temperature
that happens when a body dissipates more heat than it absorbs. In humans,
it is defined as a body core temperature below 35.0 °C (95.0 °F). Symptoms
depend on the temperature. In mild hypothermia there is shivering and
mental confusion. In moderate hypothermia shivering stops and confusion
increases. In severe hypothermia there may be paradoxical undressing, in
which a person removes his or her clothing, as well as an increased risk
of the heart stopping. Hypothermia has two main types of causes. It
classically occurs from exposure to extreme cold. It may also occur from
any condition that decreases heat production or increases heat loss.
Commonly this includes alcohol intoxication but may also include low blood
sugar, anorexia, and advanced age, among others. Body temperature is
usually maintained near a constant level of 36.5–37.5 °C (97.7–99.5 °F)
through thermoregulation. Efforts to increase body temperature involve
shivering, increased voluntary activity, and putting on warmer clothing.
Hypothermia may be diagnosed based on either a person's symptoms in the
presence of risk factors or by measuring a person's core temperature. The
treatment of mild hypothermia involves warm drinks, warm clothing and
physical activity. In those with moderate hypothermia heating blankets and
warmed intravenous fluids are recommended. People with moderate or severe
hypothermia should be moved gently. In severe hypothermia extracorporeal
membrane oxygenation (ECMO) or cardiopulmonary bypass may be useful. In
those without a pulse cardiopulmonary resuscitation (CPR) is indicated
along with the above measures. Rewarming is typically continued until a
person's temperature is greater than 32 °C (90 °F). If there is no
improvement at this point or the blood potassium level is greater than 12
mmol/liter at any time resuscitation may be discontinued. Hypothermia is
the cause of at least 1500 deaths a year in the United States. It is more
common in older people and males. One of the lowest documented body
temperatures from which someone with accidental hypothermia has survived
is 13.0 °C (55.4 °F) in a near-drowning of a 7-year-old girl in Sweden.
Survival after more than six hours of CPR has been described. In those in
whom ECMO or bypass is used survival is around 50%. Deaths due to
hypothermia have played an important role in many wars. Hyperthermia is
the opposite of hypothermia, being an increased body temperature due to
failed thermoregulation. The term is from Greek ὑπο, ypo, meaning "under",
and θερμία, thermía, meaning "heat".
Heat Escape Lessening Position
is a way to position oneself to reduce
heat loss while immersed in cold water. It is taught as part of the
curriculum in Australia, North America, and Ireland for lifeguard and
boating safety training. It involves essentially positioning one's knees
together and hugging them close to the chest using one's arms.
Furthermore, groups of people can huddle together in this position to
conserve body heat, offer moral support, and provide a larger target for
rescuers. The HELP is an attempt to reduce heat loss enough to lessen the
effect of hypothermia. Hypothermia is essentially a condition where bodily
temperature drops too low to perform normal voluntary or involuntary
functions. Cold water causes "immersion hypothermia", which can cause
damage to extremities or the body's core, including unconsciousness or
death. The HELP reduces exposure of high heat loss areas of the body.

describes a process
or reaction in which the system absorbs energy from its surroundings;
usually, but not always, in the form of heat. The term was coined by
Marcellin Berthelot from the Greek roots endo-, derived from the word "endon"
meaning "within" and the root "therm" meaning "hot." The intended sense is
that of a reaction that depends on absorbing heat if it is to proceed. The
opposite of an endothermic process is an exothermic process, one that
releases, "gives out" energy in the form of heat. Thus in each term
(endothermic & exothermic) the prefix refers to where heat goes as the
reaction occurs, though in reality it only refers to where the energy
goes, without necessarily being in the form of heat.
is a state of inactivity and
metabolic depression in endotherms. Hibernation refers to a season of
heterothermy that is characterized by low body temperature, slow breathing
and heart rate, and low metabolic rate. Although traditionally reserved
for "deep" hibernators such as rodents, the term has been redefined to
include animals such as bears and is now applied based on active metabolic
suppression rather than based on absolute body temperature decline. Many
experts believe that the processes of daily torpor and hibernation form a
continuum and utilize similar mechanisms. The equivalent during the summer
months is known as aestivation. Some reptile species (ectotherms) are said
to brumate, or undergo brumation, but any possible similarities between
brumation and hibernation are not firmly established. Some insects, such
as the wasp Polistes exclamans, hibernate by aggregating together in
groups in protected places called hibernacula.
Insect Winter Ecology
overwinter survival strategies of insects, which are in many respects more
similar to those of plants than to many other animals, such as mammals and
birds. This is because unlike those animals, which can generate their own
heat internally (endothermic), insects must rely on external sources to
provide their heat (ectothermic). Thus, insects sticking around in the
winter, must tolerate freezing or rely on other mechanisms to avoid
freezing. Loss of enzymatic function and eventual freezing due to low
temperatures daily threatens the livelihood of these organisms during
winter. Not surprisingly, insects have evolved a number of strategies to
deal with the rigors of winter temperatures in places where they would
otherwise not survive.

heaters is by the wavelength bands of infrared emission. Short wave or
near infrared for the range from 780 nm to 1400 nm, these emitters are
also named bright because still some visible light is emitted; Medium

of water for pain relief and treatment. The term encompasses a broad range
of approaches and therapeutic methods that take advantage of the physical
properties of water, such as temperature and pressure, for therapeutic
purposes, to stimulate blood circulation and treat the symptoms of certain
diseases. Various therapies used in the present-day hydrotherapy employ
water jets, underwater massage and mineral baths (e.g. balneotherapy,
Iodine-Grine therapy, Kneipp treatments, Scotch hose, Swiss shower,
thalassotherapy) and/or whirlpool bath, hot Roman bath, hot tub, Jacuzzi,
cold plunge and mineral bath.
Cold Shower for Health
Ice Bath Therapy
is a training regimen
usually following a period of intense exercise in which a substantial part
of a human body is immersed in a bath of ice or ice-water for a limited
duration. While it is becoming increasingly popular and accepted among
athletes in a variety of sports, the method is controversial, with a risk
of hypothermia, with the possibility of shock leading to sudden death.
Many athletes have used cold water immersion after an intense exercise
workout on the belief that it speeds up bodily recovery; however, the
internal physical processes are not well understood and remain elusive.
Generally research into the health effects of cold water immersion as part
of an athletic training regimen is inconclusive, with some studies
suggesting a mild benefit such as reducing muscle damage and discomfort
and alleviating delayed onset muscle soreness, with other studies
suggesting that cold water immersion may slow muscle growth and interfere
with an overall training regimen.

patient's pain intensity or other features. Pain scales are based on
self-report, observational (behavioral), or physiological data.
Self-report is considered primary and should be obtained if possible. Pain

often regarded as "the 5th Vital Sign".
Threshold of Pain

phenomenon. A distinction must be maintained between the
stimulus (an external thing that can be directly measured, such as with a
thermometer) and the person or animal's resulting pain perception (an
internal, subjective thing that can sometimes be measured indirectly, such
as with a visual analog scale). Although an IASP document defines "pain
threshold" as "the minimum intensity of a stimulus that is perceived as

skin. Those fibers are tipped with receptors that respond to pain-inducing
stimuli. When a stimulus is strong enough, these receptors generate an
electrical current—the pain signal.
The pain signal travels along the

allow sodium ions back and forth across cell membranes. These channels,
allow those charged particles across a membrane if the pain signal is
strong enough. (If it isn’t, the person feels no pain.)
When a pain signal reaches
the spinal cord, it continues up to the brain, where the somatosensory
cortex is primarily responsible for translating information about the
intensity of the pain signal. The brain’s motor cortex then generates the
body’s response—a shout of surprise, a jerk of a hand.
After an injury, even an
innocuous stimulus—like a warm bath or a pat on the back—can generate a
pain signal at the site of the original injury.

Somatic Nervous System
is the part of the peripheral nervous system associated with skeletal
muscle voluntary control of body movements. The SoNS consists of afferent
nerves and efferent nerves. Afferent nerves are responsible for relaying
sensation from the body to the central nervous system (CNS); efferent
nerves are responsible for sending out commands from the CNS to the body,
stimulating muscle contraction; they include all the non-sensory neurons
connected with skeletal muscles and skin. The a- of afferent and the e- of
efferent correspond to the prefixes ad- (to, toward) and ex- (out of).
Autonomic Nervous System
is a division of the peripheral nervous system that influences the
function of internal organs. The autonomic nervous system is a control

distributed widely in the brain, and are found in the spinal cord and
are produced by the central nervous system and
the pituitary gland with a principal function to inhibit the transmission
of pain signals; they may also produce a feeling of euphoria very similar
to that produced by other opioids.

are the nerves that emerge directly from the brain (including the
brainstem), in contrast to spinal
(which emerge from segments of the spinal cord). Cranial nerves
relay information between the brain and parts of the body, primarily to
and from regions of the head and neck. There are two main types: typical
and atypical trigeminal neuralgia. The typical form results in episodes of
severe, sudden, shock like pain in one side of the face that lasts for
seconds to a few minutes. Groups of these episodes can occur over a few
hours. The atypical form results in a constant burning pain that is less
severe. Episodes may be triggered by any touch to the face. Both forms may
occur in the same person. It is one of the most painful conditions and can
result in depression. The exact cause is unclear but believed to involve
loss of the myelin
around the trigeminal
nerve. This may occur due to compression from a blood vessel as the nerve
exits the brain stem, multiple sclerosis, stroke, or trauma. Less common
causes include a tumor or arteriovenous malformation. It is a type of
nerve pain. Diagnosis is typically based on the symptoms after ruling out
other possible causes such as postherpetic neuralgia. Treatment includes
medication or surgery. The anticonvulsant carbamazepine or oxcarbazepine
is the usual initial treatment and is effective in about 80% of people.
Other options include lamotrigine, baclofen, gabapentin, and pimozide.
Amitriptyline may help with the pain but opioids are not usually effective
in the typical form. In those who do not improve or become resistant to
other measures, a number of types of surgery may be tried.

II fast twitch fibers, but would have a greater inherent capacity for
physical endurance. The genetic inheritance of muscle fiber type sets the
outermost boundaries of physical strength possible (barring the use of
enhancing agents such as
), though the unique position within this envelope is
determined by training. Individual muscle fiber ratios can be determined
through a muscle biopsy. Other considerations are the ability to recruit
muscle fibers for a particular activity, joint angles, and the length of
each limb. For a given cross-section, shorter limbs are able to lift more
weight. The ability to gain muscle also varies person to person, based
mainly upon genes dictating the amounts of hormones secreted, but also on
sex, age, health of the person, and adequate nutrients in the diet. A

aerobic or anaerobic exercise
The definition of 'long' varies according to the type of exertion –
minutes for high intensity anaerobic exercise, hours or days for low
intensity aerobic exercise. Training for endurance can have a negative
impact on the ability to exert strength unless an individual also
undertakes resistance training to counteract this effect. When a person is
able to accomplish or withstand a higher amount of effort than their
original capabilities their endurance is increasing which to many
personnel indicates progress. In looking to improve ones endurance they
may slowly increase the amount of repetitions or time spent, if higher
repetitions are taken rapidly muscle strength improves while less
endurance is gained. Increasing endurance has been proven to release
endorphins resulting in a positive mind. The act of gaining endurance

disease in total. Although a greater endurance can assist the
cardiovascular system it does not imply that any cardiovascular disease
can be guaranteed to improve. "The major metabolic consequences of the
adaptations of muscle to endurance exercise are a slower utilization of
muscle glycogen and blood glucose, a greater reliance on fat oxidation,
and less lactate production during exercise of a given intensity." The
term stamina is sometimes used synonymously and interchangeably with
endurance. In military settings, endurance is considered the ability of a
force to sustain high levels of combat potential relative to its opponent
over the duration of a campaign. Endurance may also refer to an ability to
keep going through a tough situation involving hardship, stress, etc. (see

is damage to the spinal cord
that causes changes in its function, either temporary or permanent. These
changes translate into loss of muscle function, sensation, or autonomic
function in parts of the body served by the spinal cord below the level of
the lesion. Injuries can occur at any level of the spinal cord and can be
classified as complete injury, a total loss of sensation and muscle
function, or incomplete, meaning some nervous signals are able to travel
past the injured area of the cord. Depending on the location and severity
of damage along the spinal cord, the symptoms can vary widely, from pain
or numbness to paralysis to incontinence. The prognosis also ranges
widely, from full recovery in rare cases to permanent tetraplegia (also
called quadriplegia) in injuries at the level of the neck, and paraplegia
in lower injuries. Complications that can occur in the short and long term
after injury include muscle atrophy, pressure sores, infections, and
respiratory problems. In the majority of cases the damage results from
physical trauma such as car accidents, gunshots, falls, or sports
injuries, but it can also result from nontraumatic causes such as
infection, insufficient blood flow, and tumors. Athletes are especially
susceptible to becoming involved in high collision spinal injuries. Some
of the more common injuries include any type of sprain and strain of the
spinal cord. These injuries can either occur alone, or with another spinal
disease. Dislocations and fractures are also common in spine injuries.
Efforts to prevent SCI include individual measures such as using safety
equipment, societal measures such as safety regulations in sports and
traffic, and improvements to equipment. Known since ancient times to be a
catastrophic injury and long believed to be untreatable, SCI has seen
great improvements in its care since the middle of the 20th century.
Treatment of spinal cord injuries starts with stabilizing the spine and
controlling inflammation to prevent further damage. Other interventions
needed can vary widely depending on the location and extent of the injury,
from bed rest to surgery. In many cases, spinal cord injuries require
substantial, long-term physical and occupational therapy in
rehabilitation, especially if they interfere with activities of daily
living. Research into new treatments for spinal cord injuries includes

is a type of cosmetic procedure or physical therapy tool which promises to
alter facial contours by means of increasing muscle tone, and facial
volume by promoting muscular hypertrophy, and preventing muscle loss due
to aging or facial paralysis. Facial toning and exercise is therefore in
part a technique to achieve facial rejuvenation by reducing wrinkles,
sagging and expression marks on the face and skin. As a physical therapy,
facial toning is used for victims of stroke and forms of facial paralysis
such as Bell’s palsy. Facial toning achieves this by performing facial
muscle exercising. There are two types of facial toning exercises: active

Shared Decision Making
(Informed Medical Decisions) The 12 questions every patient
should ask doctors and nurses.
After admission, ask the names of your primary hospital doctor and the
other specialists who make up your physician team. Your primary hospital
physician will coordinate with the team, and your nurses will assist you
during your stay.2
. Ask your physician:
What is my main diagnosis, and are there any other newly diagnosed issues?
Feel free to express your fears and anxieties about your diagnosis to the
physicians and nursing staff. Don’t let the anxiety build until it becomes
. Ask your nurse or
physician: How are my illnesses responding to treatment? Ask the nursing
staff in particular about how your condition is progressing and how you
can facilitate your recovery. It’s your fundamental right to obtain
information regarding your medical condition. Understanding both your
diagnosis and your treatment plan is a central tenet of the Patient’s Bill
of Rights, which was adopted by the Association of American Physicians and
Surgeons in 1995. According to this document, all patients are entitled
“to be informed about their medical condition, the risks and benefits of
treatment, and appropriate alternatives.”

Ask your family, friends, or other trusted individuals to be involved and
help support you in your recovery. Yes, it’s hard to put ourselves in a
situation where we feel like we’re burdening someone or losing our
independence, even for a little while. Understand that these people are an
integral part of your treatment team and contribute to the success of your

related to your stay. The social worker is there to help clarify what your
insurance covers and how much you may be required to pay. If you need
assistance with payment, discuss the options available to you with the
social worker before you leave as well.6
Ask to see the nurse manager or charge nurse if you’re experiencing
ongoing issues with care or communication about your condition. The person
in this role is responsible for helping patients and easing any
misunderstanding or tensions that may arise during your stay.
. As you approach discharge, ask if you
should continue taking any of the medications (including vitamins and
supplements) you took before you were admitted. This information should be
included in your discharge instructions, but take the time to fully
understand this aspect of your care to avoid potentially disastrous or
even fatal complications later.8.
the staff to show you and your caregivers how to perform any tasks
prescribed for after you’ve left the hospital, especially any treatments
that may require a special skill, such as changing a bandage or giving an
injection. Ask the nurse or physician to remain in your room while you
practice to ensure you’re doing it correctly.9
Ask your nurse or physician if it’s safe to perform ordinary tasks alone,
like bathing, dressing, driving, or exercising. Make sure you’ve arranged
for help with any of these activities before you leave the hospital.
. Ask your nurse or physician if you can
or should use any medical equipment, such as a walker, brace, or health
monitor, to help with your recovery and comfort. If the answer is yes, ask
for assistance in obtaining these items before you leave or shortly after
your return home.11
. At the time of
your discharge, ask the discharge nurse any questions you have about your
discharge information. You should have been provided with printed
discharge instructions. Don’t leave the hospital without obtaining these,
reading them (or having them read to you), and making sure you
understanding all of the information they cover.

occur internally, where blood leaks from blood vessels inside the body, or
externally, either through a natural opening such as the mouth, nose, ear,
urethra, vagina or anus, or through a break in the skin. Hypovolemia is a
massive decrease in blood volume, and death by excessive loss of blood is
referred to as exsanguination. Typically, a healthy person can endure a
loss of 10–15% of the total blood volume without serious medical
difficulties (by comparison, blood donation typically takes 8–10% of the
donor's blood volume). The stopping or controlling of bleeding is called
hemostasis and is an important part of both first aid and surgery.
Vetigel Stops Bleeding
(also known as clotting) is
the process by which blood changes from a liquid to a gel, forming a blood
clot. It potentially results in hemostasis, the cessation of blood loss
from a damaged vessel, followed by repair. The mechanism of coagulation
involves activation, adhesion, and aggregation of platelets along with
deposition and maturation of fibrin. Disorders of coagulation are disease
states which can result in bleeding (hemorrhage or bruising) or
obstructive clotting (thrombosis).

thrombus is a healthy response to injury intended to prevent bleeding, but
can be harmful in thrombosis, when clots obstruct blood flow through
healthy blood vessels.

measurements of blood pressure. Less commonly, "mechanic's stethoscopes"
are used to listen to internal sounds made by machines, such as diagnosing
a malfunctioning automobile engine by listening to the sounds of its
internal parts. Stethoscopes can also be used to check scientific vacuum
chambers for leaks, and for various other small-scale acoustic monitoring
tasks. A stethoscope that intensifies auscultatory sounds is called
is the speed of the heartbeat measured by the number of contractions of
the heart per minute (bpm). The heart rate can vary according to the
body's physical needs
, including the need to absorb oxygen and excrete
. It is usually equal or close to the pulse measured at any
peripheral point. Activities that can provoke change include
, sleep, anxiety, stress, illness, and ingestion of drugs.
Heart Rate Variability
is the physiological phenomenon of
variation in the time interval between heartbeats. It is measured by the
variation in the beat-to-beat interval.
is the process of recording the electrical
activity of the heart over a period of time using electrodes placed on the
skin. These electrodes detect the tiny electrical changes on the skin that
arise from the heart muscle's electrophysiologic pattern of depolarizing
and repolarizing during each heartbeat. It is a very commonly performed
cardiology test. In a conventional 12-lead ECG, 10 electrodes are placed
on the patient's limbs and on the surface of the chest. The overall
magnitude of the heart's electrical potential is then measured from 12
different angles ("leads") and is recorded over a period of time (usually
10 seconds). In this way, the overall magnitude and direction of the
heart's electrical depolarization is captured at each moment throughout
the cardiac cycle. The graph of voltage versus time produced by this
noninvasive medical procedure is referred to as an electrocardiogram.
During each heartbeat, a healthy heart has an orderly progression of
depolarization that starts with pacemaker cells in the sinoatrial node,
spreads out through the atrium, passes through the atrioventricular node
down into the bundle of His and into the Purkinje fibers, spreading down
and to the left throughout the ventricles. This orderly pattern of
depolarization gives rise to the characteristic ECG tracing. To the
trained clinician, an ECG conveys a large amount of information about the
structure of the heart and the function of its electrical conduction
system. Among other things, an ECG can be used to measure the rate and
rhythm of heartbeats, the size and position of the heart chambers, the
presence of any damage to the heart's muscle cells or conduction system,
the effects of cardiac drugs, and the function of implanted pacemakers.

when the heart quivers instead of pumps due to disorganized electrical
activity in the ventricles. It results in cardiac arrest with loss of
consciousness and no pulse. This is followed by irreversible death without
treatment. Ventricular fibrillation is found initially in about 10% of
people in cardiac arrest.

Types of murmurs are due to structural defects in the heart itself.

is a genetic disorder of the connective tissue. The
degree to which people are affected varies. People with Marfan tend to
be tall, and thin, with long arms, legs, fingers and toes. They also
typically have flexible joints and scoliosis. The most serious
complications involve the heart and aorta with an increased risk of mitral
valve prolapse and aortic aneurysm. Other commonly affected areas include
the lungs, eyes, bones and the covering of the spinal cord.

is a term referring to the fraction of
-saturated hemoglobin relative to total hemoglobin (unsaturated +
saturated) in the blood. The human body requires and regulates a very
precise and specific balance of oxygen in the blood. Normal blood oxygen
levels in humans are considered 95-100 percent. If the level is below 90
percent, it is considered low resulting in
. Blood oxygen levels
below 80 percent may compromise organ function, such as the brain and
heart, and should be promptly addressed. Continued low oxygen levels may
lead to respiratory or cardiac arrest. Oxygen therapy may be used to
assist in raising blood oxygen levels. Oxygenation occurs when oxygen
molecules (O2) enter the tissues of the body. For example, blood is
oxygenated in the lungs, where oxygen molecules travel from the air and
into the blood. Oxygenation is commonly used to refer to medical oxygen

is a noninvasive method for monitoring a person's oxygen saturation (SO2).
Its reading of SpO2 (peripheral oxygen saturation) is not always
identical to the reading of SaO2 (arterial oxygen saturation) from
arterial blood gas analysis, but the two are correlated well enough that
the safe, convenient, noninvasive, inexpensive pulse oximetry method is
valuable for measuring oxygen saturation in clinical use. In its most
common (transmissive) application mode, a sensor device is placed on a
thin part of the patient's body, usually a fingertip or earlobe, or in the
case of an infant, across a foot. The device passes two wavelengths of
light through the body part to a photodetector. It measures the changing
absorbance at each of the wavelengths, allowing it to determine the
absorbances due to the pulsing arterial blood alone, excluding venous
blood, skin, bone, muscle, fat, and (in most cases) nail polish.
Reflectance pulse oximetry may be used as an alternative to transmissive
pulse oximetery described above. This method does not require a thin
section of the person's body and is therefore well suited to a universal
application such as the feet, forehead, and chest, but it also has some
limitations. Vasodilation and pooling of venous blood in the head due to
compromised venous return to the heart, as occurs with congenital cyanotic
heart disease patients, or in patients in the Trendelenburg position, can
cause a combination of arterial and venous pulsations in the forehead
region and lead to spurious SpO2 results.
