6. Taste buds:
   1. is the common name for papillae (on the tongue)
   2. are clustered based on taste – sweet ones at the tip of the tongue and sour ones more on the side of the tongue, for example
   3. both a. and b. are correct
   4. neither a. nor b. is correct

Answer 1

Answer

36) Gustation :

• Involves one or more cranial nerves sending signals to the brain
  - Three cranial nerves are involves : Vagus, glossopharyngeal and facial nerves.
  
• Involves basal cells which can differentiate into new taste receptor cells
  - Basal cells are located near the taste buds that differential into taste receptors (taste buds)

Option C) Both a. and b. are correct

37) Taste buds :

• Are clustered based on taste – sweet ones at the tip of the tongue and sour ones more on the side of the tongue

- Papillae on the surface on tongue contains taste receptors commonly known as taste buds.
- There are four types of papillae out of which only three types contain taste buds.
- Hence, taste bud are not common name for papillae.

Option B
