GENERAL HISTOLOGY

Detailed explanation-1: -There are four types of papillae, divided into: filiform, fungiform, circumvallate and foliated. Taste buds, which appear as oval shapes which look pale in histology sections, are present in the fungiform, foliated and circumvallate papillae, but not in the filiform1, 2, 3, 4.

Detailed explanation-2: -Your tongue has between 200 and 400 fungiform papillae that range across the dorsum or top of the tongue but are mostly concentrated on the sides and the tip. Each papilla contains three to five taste buds, adding up to more than 1, 500 receptors overall.

Detailed explanation-3: -Atrophic glossitis is a condition characterised by absence of filiform or fungiform papillae on the dorsal surface of the tongue.
