  1. Foliate papillae

  2. Fungiform papillae

  3. Filiform papillae

  4. None of the above

Show answer
Correct Option: C
Explanation:

On the tongue, papillae are situated anteriorly to the sulcus terminalis. There are three types of papillae on the tongue: filiform papillae, circumvallate papillae and fungiform papillae. The filiform papillae are the smallest and most abundant. They help in holding the food. Circumvallate papillae are large papillae arranged in a "V" shape. Fungiform papillae are mushroom shaped. Taste buds are found on circumvallate and fungiform. 

Thus, the correct answer is option C.

  1. Papillae

  2. Lingual septum

  3. Terminal sulcus

  4. Lingual sulcus

Show answer
Correct Option: C
Explanation:

  • Terminal sulcus of the tongue is a V-shaped groove, with a posteriorly oriented apex, on the surface of the tongue, marking the separation between the anterior (oral or horizontal) and the posterior (pharyngeal or vertical) parts of the tongue. Hence, Terminal sulcus separates the two parts of the tongue.

  1. Dorsum

  2. Tastant

  3. Saliva

  4. None of the above

Show answer

  1. Cuboidal cells

  2. Columnar cells

  3. Ciliated cells

  4. None of the above

Explanation:

The taste buds are comprised of two main type of cells, receptor cell and the supporting cell. The receptor cells are neurosensory. They have one free end and the other nerve ending travelling to the taste area of the brain. The supporting cells are the columnar cells. These cells are present between the receptor cells. These cells are about 40 in number. 

Thus, the correct answer is option B.
