Question

Fungiform papillae carry which of the following cranial nerve?

• A. VII
• B. IX
• C. X
• D. None of the above

Answer 1

The correct option is A VII

• Fungiform papillae contain taste buds (especially for bitter taste), temperature receptors and have a good blood supply. They are scattered over the top and sides of the tongue, mainly towards the tip.
• Cranial nerves are the nerves which arise from the brain and spinal cord. The facial nerve is the 7th cranial nerve it arises from the pons of the brain stem.
• The fungiform papillae are innervated by the VII cranial nerve. Hence through 7th cranial nerve fungiform papillae send sensory signals of taste to the brain stem.
• So, the correct answer is 'VII'.
