• Fungiform papillae - as the name suggests, are slightly mushroom shaped if looked at in
section. These are present mostly at the apex (tip) of the tongue.
• Filiform papillae - these are thin, longer papillae that don't contain taste buds but are the
most numerous. These papillae are mechanical and not involved in gustation.
• Foliate papillae - these are ridges and grooves towards the posterior part of the tongue.
• Circumvallate papillae - there are only about 3-14 of these papillae on most people and
they are present at the back of the oral part of the tongue. They are arranged in a circular-shaped
row just in front of the sulcus terminalis of the tongue.
Structure of Taste Buds
The mouth cavity. The cheeks have been slit transversely and the tongue pulled
forward.
Each taste bud is flask-like in shape, its broad base resting on the corium, and its neck opening by
an orifice, the gustatory pore, between the cells of the epithelium.
The bud is formed by two kinds of cells: supporting cells and gustatory cells.
