What type of papillae on the tongue contains taste buds?

The correct answer indicates that both circumvallate and fungiform papillae contain taste buds, which is an important aspect in understanding the anatomy and function of the tongue in relation to gustation (the sense of taste).

Circumvallate papillae are large and found at the back of the tongue arranged in a V-shape. They each contain numerous taste buds embedded in the sides and are particularly responsive to bitter tastes. On the other hand, fungiform papillae are smaller and more mushroom-shaped, distributed across the surface of the tongue, primarily at the tip and sides. These also contain taste buds, primarily responding to sweet and salty flavors.

Filiform papillae, while present in large numbers on the tongue, do not contain taste buds and are primarily responsible for the texture and mechanical aspects of the tongue's surface, aiding in the manipulation of food. Understanding these differences highlights the specialized role of circumvallate and fungiform papillae in taste perception, making the selection of both as correct a reflection of the tongue's taste capabilities.
