What is the difference between filiform and fungiform papillae?

Filiform papillae are the most common. They are keratinised and in the living, they look white. Fungiform papillae are not keratinised, but are highly vascularised. In the living, they look red.

What is the difference between filiform Fungiform mushroom like foliate and Circumvallate papillae?

Each fungiform papillae usually contains 3-5 taste buds. Like circumvallate papillae, foliate papillae also contain more than 100 taste buds each. A fourth type of papillae, filiform, also exists, but does not contain any taste buds. Each taste bud consists of 30-100 taste receptor cells.

What are foliate papillae?

The foliate papillae are leaf shaped with taste buds on the side of the papillae, and these are along the border. The circumvallate papillae contain taste buds along the sides of whorls and are located in the posterior third of the tongue in the shape of a V.

Which are types of papillae?

The dorsal surface of the mammalian tongue is covered with four kinds of papillae, fungiform, circumvallate, foliate and filiform papillae. With the exception of the filiform papillae, these types of papillae contain taste buds and are known as the gustatory papillae.

What kind of epithelium covers these two papillae?

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 papillae and covered by stratified squamous epithelium.

What is the function of the papillae?

Filiform papillae serve a mechanical purpose. With their somewhat stiff form, they function like a gripping surface to help draw food into the mouth. Rubbing the tongue over the inside of the mouth can help to remove residue left by food, drink, or medicine.
