Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue.

Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
