taste receptor

A gustatory cell of a taste bud.
See also: receptor


the peculiar sensation caused by the contact of soluble substances with the tongue; the sense effected by the tongue, the gustatory and other nerves, and the gustatory center.
There are four basic tastes: sweet, salt, sour and bitter. Sometimes alkaline and metallic are also included as basic tastes. All other tastes are combinations of these. The taste buds are specialized, and each responds only to the kind of basic taste that is its specialty. The location of and the number of taste buds varies between animal species.
Other senses, including smell and touch, also play an important role in tasting.

taste bud, taste organ
the organ of taste; spherical nests of cells embedded in the mucosa of the mouth and tongue are composed of supporting and gustatory cells. The gustatory cells have a delicate, hairlike process which protrudes from the peripheral surface of the cell. Substances must be in solution to be tasted, solids must be chewed and mixed with saliva.
conditioned taste aversion
animals have been shown to develop aversions to foods associated with illness or other adverse experiences.
conditioned taste preference
theoretically, the reverse of conditioned taste aversion, which is a naturally occurring phenomenon; it is not widely accepted that animals will associate recovery from illness with a specific taste or food.
taste pore
opening from the exterior to a taste bud.
taste receptor
one of the three types of cell in a taste bud; called also gustatory cells.
