Question

The type of papillae with taste buds present in rabbit but absent in human is/are
A. Circumvallate
B. Circumvallate and foliate
C. Foliate
D. Fungiform

Answer 1

Hint: Taste buds have taste receptors or also called gustatory receptors which are a kind of sensory receptors. They are located on papillae structures. There are a total of four types of papillae present, out of which humans only have three.

Complete answer: Foliate papillae are called foliate because they are leaf-shaped. They are in the form of ridges and grooves at the posterior end of the tongue. The taste buds are present along the side of the papillae. Foliate papillae are innervated by anterior and posterior papillae. They are present in rabbits but not in humans.
-Circumvallate papillae are arranged in a circular shape in front of the sulcus terminalis of the tongue. Only 10 to 14 of these papillae are present in humans at the back of the oral part of the tongue in the shape of a V and have around 100 taste buds along the side of whorls. They are present in both humans and rabbits.
-Circumvallate papillae are present in humans.
-Fungiform papillae are mushroom-shaped and have taste buds in the middle or on the cleft of the papillae. They are innervated by facial nerves and are present on the dorsal side of the tongue and also on the sides. They are present both in humans and in rabbits.
Hence, the correct answer is an option (C).

Note: Papillae are nodules on the tongue which allow the increase in the surface area for taste buds. Taste buds can sense the taste of the food to be bitter, sour, sweet, and salty based on the location they are present.
