GENERAL HISTOLOGY

Detailed explanation-1: -523-7, the legend in Figure 3 reads: “Fungiform and filiform papillae, over which are the taste buds”. However, filiform papillae do not have taste buds6.

Detailed explanation-2: -A fourth type of papilla, filiform papillae, are devoid of taste buds and are believed to be involved in texture perception, but the details of both the mechanical and molecular aspects of filiform papillae in encoding food texture are still unknown.

Detailed explanation-3: -Papillae are the tiny raised protrusions on the tongue that contain taste buds. The four types of papillae are filiform, fungiform, foliate, and circumvallate. Except for the filiform, these papillae allow us to differentiate between sweet, salty, bitter, sour, and umami (or savory) flavors.
