Sense of Taste

Taste buds are the special organs of taste. They resemble orange sections and are primarily located on the surface of the tongue where they are associated with tiny elevations called papillae (figs. 12.8 and 12.9). Taste buds are also scattered in the roof of the mouth, the linings of the cheeks, and the walls of the pharynx.
