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.

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.
