The taste buds and the sense of taste: Short Overview
The gustatory papillae are found covering the dorsal surface of the tongue, giving it a rough appearance.
These are three principal components of the sense of taste: the receptor organs, which are the gustatory papillae; the gustatory pathways, via the glossopharyngeal, vagus and lingual nerves, running to the hippocampal gyrus; and the gustatory centers, which are found in this region.
