  3. Papilla pore

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Papillae give the tongue its rough texture. The surface of the papillae is covered by thousands of taste buds.
Taste buds have the taste sensors or the taste receptors inside them.
Each taste bud has a cavity with a pore called as the taste pore.
Inside each cavity is taste receptor cells or gustatory receptor cells, bathed in saliva.
Each receptor cell has a free hair-like cilium also called as the taste hair which projects into the outer taste pore.
Additionally, each receptor cell has a nerve fibre called as the gustatory nerve extending from its base to the taste centre of the brain.
