GENERAL HISTOLOGY

Detailed explanation-1: -Circumvallate papillae form an inverted V at the posterior of the tongue. These papillae are embedded into the tongue and have a moat around them. Humans have over 100 taste buds in the circumvallate papillae (Figure 1).

Detailed explanation-2: -Fungiform papillae are most numerous around the tip of the tongue, whereas circumvallate papillae are arranged in a ‘V’ pattern on the posterior third of the tongue immediately anterior to the sulcus terminalis. 8 The taste buds on the fungiform papilla are mostly embedded on the surface of the papilla.

Detailed explanation-3: -According to the map, we detect sweetness on the tip of our tongue, bitterness at the back, and saltiness and sourness along the sides.
