taste bud

one of a number of flask-shaped cell nests located in the epithelium of vallate, fungiform, and foliate papillae of the tongue and also in the soft palate, epiglottis, and posterior wall of the pharynx; it consists of sustentacular, gustatory, and basal cells between which the intragemmal sensory nerve fibers terminate. There are five basic types of taste, each exemplified by the substance(s) in parenthesis after their types: bitter (quinine), salty (NaCl), sour (HCl), sweet (sugars and artificial sweeteners), and umami (glutamic acid).

taste bud

n.
Any of numerous spherical or ovoid clusters of receptor cells found mainly in the epithelium of the tongue and constituting the end organs of the sense of taste.

taste bud

any one of many peripheral taste organs distributed over the tongue, epiglottis, and the roof of the mouth. The five basic taste sensations registered by chemical stimulation of the taste buds are sweet, sour, bitter, savory, and salty. All other tastes perceived are combinations of these five basic flavors plus the input from olfactory receptors. Each taste bud rests in a spheric pocket, which extends through the epithelium. Gustatory cells and supporting cells form each bud, which has a surface opening and an opening in the basement membrane. Also called gustatory organ.

taste bud

One of the many spherical nests of cells containing specialized nerve endings distributed over the edges and base of the tongue. The taste buds respond to the crude flavours of substances dissolved in saliva. See also TASTE.

taste bud

a receptor organ of taste that contains groups of slender modified epithelial cells with hair-like microvilli zwhich are clustered in a small external pore. Taste buds are associated with the mouth in vertebrates, but in fish they also occur over the body surface and on the fins. They are found on the tarsi of some insects (e.g. DIPTERANS). Humans distinguish between sweet, salt, sour and bitter tastes, using taste buds in different locations on the tongue, sweet on the front, sour on the sides, bitter on the back and salt all over. Taste depends on the relative activity of neurones that innervate the taste buds and not on any structural differences in the buds.

Several flask-shaped cell nests located in epithelium of vallate, fungiform, and foliate papillae of tongue and also in soft palate, and elsewhere. There are five basic taste classifications, each exemplified by substance(s) in parenthesis after their types: bitter (quinine), salty (NaCl), sour (HCl), sweet (sugars and artificial sweeteners), and umami (glutamic acid).
