The sense of taste is called gustation. The specialized sense organs for taste are called papillae, and are found in the mouth, mainly on the tongue.
Papillae are small projections containing many taste buds.
Each taste bud resembles a tiny orange and consists of supporting cells and taste cells. The outer edge of the taste cells are arranged around a tiny taste pore. These microvilli provide the receptor surface for taste. Interwoven among the taste cells is a branching terminal of several taste nerve fibers that are stimulated by the taste receptor cells. The taste cell is negatively charged inside.
