Are lingual tonsils taste buds?

Taste buds, the receptors of the gustatory sense, are scattered over the mucous membrane of their surface. Serous glands drain into the folds and clean the taste buds. Lingual tonsils are found immediately behind the foliate papillae and, when hyperplastic, cause a prominence of the papillae.

Taste receptor cells sense various chemical compounds in foods and transmit these signals through gustatory nerve fibers to the central nervous system. These sensory signals are vitally important for life; they provide information about which prospective foods are nutritious and warnings as to those that are noxious.
