Which type of papillae is primarily located at the back of the tongue?

• A. Fungiform papillae
• B. Foliate papillae
• C. Vallate papillae
• D. Filiform papillae

Answer: (C)

Vallate papillae, also known as circumvallate papillae, are primarily located at the back of the tongue and are characterized by their large, dome-shaped structure surrounded by a trench. These papillae contain numerous taste buds in their sides, which are crucial for the perception of taste. Their strategic position at the rear of the tongue helps in detecting the flavors of food as they are swallowed, playing a critical role in the gustatory system. Fungiform papillae, predominantly located on the anterior part of the tongue, and foliate papillae, found on the sides of the tongue, have different roles and locations. Filiform papillae, which do not contain taste buds, are responsible primarily for the texture perception of food and help create a rough surface on the tongue. The identification of vallate papillae as the correct answer highlights their distinct anatomical features and functional significance in taste sensation.
