Gustatory Cells in Taste Buds and Related Sensory Cells
Taste buds are chemoreceptor end-organs for taste. In man, most of them occur in the stratified squamous epithelium of the dorsal surface of the tongue concentrated in the circumvallate, foliate, and fungiform papillae. A small number of taste buds also exist in the stratified squamous epithelium of the soft palate, lower part of the pharynx, and laryngeal surface of the epiglottis. The sense of taste, however, is widely distributed in the oral cavity and pharynx. The structural and functional differentation of taste buds corresponding to the four kinds of taste sensation, i.e., sweet, bitter, sour, and salty, is unknown. Thus, it is still to be established how important a role in taste sensation is played by taste buds.
