Filiform papillae cover most of the dorsal surface of the anterior 2/3 of the tongue, with fungiform interspaced. Just in front of the sulcus terminalis lies a V-shaped line of circumvallate papillae, and on the posterior aspects of the lateral margins of the tongue lie the foliate papillae.
There are three types of papillae involved in taste: fungiform papillae, foliate papillae, and circumvallate papillae. (The fourth type - filiform papillae do not contain taste buds). Beyond the papillae, taste receptors are also in the palate and early parts of the digestive system like the larynx and upper esophagus.
Fungiform papillae - as the name suggests, these are slightly mushroom-shaped if looked at in longitudinal section. These are present mostly at the dorsal surface of the tongue, as well as at the sides. Innervated by facial nerve. Foliate papillae - these
Human Von Ebner's gland. Von Ebner's glands, also called Ebner's glands or gustatory glands, are exocrine glands found in the mouth. More specifically, they are serous salivary glands which reside adjacent to the moats surrounding the circumvallate and foliate papillae just anterior to the posterior third of the tongue in its submucosa, anterior to the terminal sulcus.
Prevalence in human populations varies between 65% and 81%. [2]There is no statistically significant sexual dimorphism in this trait. A 1940 study by Alfred Sturtevant analyzed 282 people of mostly European ancestry and observed that 67.1% of females and 62.9% of males could roll their tongues, and the remaining could not do it.

Hairy tongue largely occurs in the central part of the dorsal tongue, just anterior (in front) of the circumvallate papillae, although sometimes the entire dorsal surface may be involved. [6] Discoloration usually accompanies hairy tongue, and may be yellow, brown or black. [ 6 ]
A supertaster is a person whose sense of taste is significantly more sensitive than most. The cause of this heightened response is likely, at least in part, due to an increased number of fungiform papillae. [117] Studies have shown that supertasters require less fat and sugar in their food to get the same satisfying effects.
Median rhomboid glossitis is a condition characterized by an area of redness and loss of lingual papillae on the central dorsum of the tongue, sometimes including lesions of the tongue and palate.
