The taste papillae are folds on your tongue. They are necessary for increasing the surface area of your tongue. There are three types of taste papillae on your tongue:
1.
Mushroom-shaped papillae
(Fungiform papillae)
These are located on the front two thirds of the tongue; they are
embedded with an average of four taste buds.
2.
Circumvallate papillae (Vallate papillae)
These are large
dome-shaped papillae which lie in a V-shape on the rear part of the tongue.
They are embedded with an average of 250 taste buds.
3.
Leaf-shaped papillae (Foliate papillae)
These papillae
lie along the length of the tongue and are embedded with about 1300 taste buds.
Taste buds are
therefore found on the taste papillae. In Figures you can see a microscopic
image of a taste bud. Taste cells are located in the taste bud.
