Sense of Taste
Sweet - Salty - Sour - Bitter
is one of the five traditional
that belongs to
the gustatory system. Taste is the sensation produced when a substance in
the mouth reacts chemically with taste receptor cells located on taste
buds in the oral cavity, mostly on the tongue. Taste, along with smell
(olfaction) and trigeminal nerve stimulation (registering texture, pain,
and temperature), determines flavors of food or other substances. Humans
have taste receptors on taste buds (gustatory calyculi) and other areas
including the upper surface of the tongue and the epiglottis.
Every Flavor is a Chemical Compound

oral cavity from the nasal cavity. The palate is divided into two parts,
the anterior bony hard palate, and the posterior fleshy soft palate (or

(i.e., pleasure) provided by foods or fluids that are agreeable to the
"palate", which often varies relative to the homeostatic satisfaction of
nutritional, water, or energy needs. The palatability of a food or fluid,
unlike its flavor or taste, varies with the state of an individual: it is
lower after consumption and higher when deprived. Palatability of foods,
however, can be learned. It has increasingly been appreciated that this
can create a hedonic hunger that is independent of homeostatic needs.
is a muscular organ in the mouth of most vertebrates that manipulates food
for mastication, and is used in the act of swallowing. It is of importance
in the digestive system and is the primary organ of taste in the gustatory
system. The tongue's upper surface (dorsum) is covered in taste buds
housed in numerous lingual papillae. It is sensitive and kept moist by
saliva, and is richly supplied with nerves and blood vessels. The tongue
also serves as a natural means of cleaning the teeth. A major function of
the tongue is the enabling of speech in humans and vocalization in other
contain the taste receptor cells, which are also known as
gustatory cells. The taste receptors are located around the small
structures known as papillae found on the upper surface of the tongue,
soft palate, upper esophagus, the cheek and epiglottis. These structures
are involved in detecting the five elements of taste perception: salty,
sour, bitter, sweet and umami; through the combination of these elements
we detect "flavors." A popular myth assigns these different tastes to
different regions of the tongue; in reality these tastes can be detected
by any area of the tongue. Via small openings in the tongue epithelium,
called taste pores, parts of the food dissolved in saliva come into
contact with the taste receptors. These are located on top of the taste
receptor cells that constitute the taste buds. The taste receptor cells
send information detected by clusters of various receptors and ion
channels to the gustatory areas of the brain via the seventh, ninth and
tenth cranial nerves. On average, the human tongue has 2,000–8,000 taste
is a type of receptor which facilitates the sensation of taste. When food
or other substances enter the mouth, molecules interact with saliva and
are bound to taste receptors in the oral cavity and other locations.
Molecules which give a sensation of taste are considered "sapid". Taste
receptors are divided into two families: Type 1, sweet, first
characterized in 2001: TAS1R2 – TAS1R3. Type 2, bitter, first
characterized in 2000: TAS2R1 – TAS2R50, and TAS2R60. Combinations of
these receptors in dimers or other complexes contributes to different
perceptions of taste. Visual, olfactive, “sapictive” (the perception of
tastes), trigeminal (hot, cool), mechanical, all contribute to the
perception of taste. Of these, transient receptor potential cation channel
subfamily V member 1 (TRPV1) vanilloid receptors are responsible for the
perception of heat from some molecules such as capsaicin, and a CMR1
receptor is responsible for the perception of cold from molecules such as
menthol, eucalyptol, and icilin.

transcription factor involved in the regulation of biological responses to
planar aromatic (aryl) hydrocarbons. This receptor has been shown to

is the sense of smell. This sense is mediated by specialized sensory cells
of the nasal cavity of vertebrates, which can be considered analogous to
sensory cells of the antennae of invertebrates. In humans, olfaction
occurs when odorant molecules bind to specific sites on the olfactory
receptors. These receptors are used to detect the presence of smell. They
come together at the glomerulus, a structure which transmits signals to
the olfactory bulb (a brain structure directly above the nasal cavity and
below the frontal lobe).
is the part of the sensory
used for smelling (olfaction). Most mammals and reptiles have a
main olfactory system and an accessory olfactory system. The main
olfactory system detects airborne substances, while the accessory system
senses fluid-phase stimuli. The senses of smell and taste (gustatory
system) are often referred to together as the chemosensory system, because
they both give the brain information about the chemical composition of
objects through a process called transduction.

loss of the sense of smell. Anosmia may be temporary, but some anosmia
(including traumatic anosmia) can be permanent. Anosmia is due to a number
of factors, including an inflammation of the nasal mucosa, blockage of
nasal passages or a destruction of one temporal lobe. Inflammation is due
to chronic mucosa changes in the paranasal sinus lining and the middle and
is the temporary, normal inability to distinguish a
particular odor after a prolonged exposure to that airborne compound. For
example, when entering a restaurant initially the odor of food is often
perceived as being very strong, but after time the awareness of the odor
normally fades to the point where the smell is not perceptible or is much
weaker. After leaving the area of high odor, the sensitivity is restored
with time. This is one of the reasons why we can't tell how bad we smell
because we adapt to smells very quickly.
is an olfactory dysfunction that is characterized by the inability of the
brain to properly identify an odor's "natural" smell. What happens
instead, is that the natural odor is transcribed into what is most often
described as an unpleasant aroma, typically a "'burned,' 'rotting,'
'fecal,' or 'chemical' smell." There are instances, however, of pleasant
odors. This is more specifically called euosmia (Gk.).
