taste receptors on tongue

The receptors for sweet, bitter, sour and umami tastes are proteins (produced and coded for by particular genes in our DNA) found on the surface of the cells. Taste receptors were first described as sensory receptors located on the tongue, where they are expressed in small clusters of specialized epithelial cells. Taste receptor cells, with which incoming chemicals from food and other sources interact, occur on the tongue in groups of 50–150.Each of these groups forms a taste bud, which is grouped together with other taste buds into taste papillae. The nucleus of the solitary tract projects to a specific gustatory nucleus in the thalamus, and from there to the insular cortex. Taste receptors in the tongue send information via the 7th and 9th cranial nerves to reach the nucleus of the solitary tract in the hindbrain. • Our experts can answer your tough homework and study questions.
