Fungiform papillae, magnified and sectional diagram. The fungiform papillae are club shaped projections on the tongue, generally red in color. They are found on the tip of the tongue, scattered amongst the filiform papillae but are mostly present on the tip and sides of the tongue.
Filiform papillae: They are thin, elongated and resemble a v-shape. These help in identifying the sour taste and also are the abrasive cover for the tongue.
Fungiform papillae: These are most often scattered on the whole tongue but more on the sides or the tip of the tongue. Foliate papillae: These can be found on the sides of the tongue and are formed into two clusters, both with an extended fold.

Vallate papillae – Papillae vallatae. The papilla is shaped like a truncated cone, the smaller end being directed downward and attached to the tongue, the broader part or base projecting a little above the surface of the tongue and being studded with numerous small secondary papillæ and covered by stratified squamous epithelium.
The circumvallate papillae (or vallate papillae) are dome-shaped structures on the human tongue that vary in number from 8 to 12. They are situated on the surface of the tongue immediately in front of the foramen cecum and sulcus terminalis, forming a row on either side; the two rows run backward and medially, and meet in the midline.
The number of vallate papillae per human tongue varies between 4 and 18 (n = 2264 tongues), with an average of 9.2 ± 1.8 papillae ( Münch, 1896 ). Ninety-eight percent of all tongues have a central median papilla ( Fig. 2 C).
