Document Summary
The receptors for taste (gustation) and smell (olfaction) are classified as chemoreceptors because they respond to chemical substances. Taste buds - taste receptors occur in taste buds in the mucosa of the mouth and pharynx. About 10,000 taste buds on surface of tongue. A few taste buds occur on the posterior region of the palate (roof of mouth), on the inner surface of the cheeks, on the posterior wall of the pharynx, and on the epiglottis. Most taste buds occur in peglike projections of the tongue mucosa called papillae: taste buds occur within the epithelium that covers the papillae. In the small fungiform papillae scattered over the entire surface of the tongue, the taste buds are on the apical surface. In the large vallate papillae arranged in an inverted v near the back of the tongue, the taste buds are in the side walls.
