Tamiku [17]

Answer:

The correct answer is D. The seventh cranial nerve is the facial nerve.

Explanation:

The facial nerve is a mixed cranial nerve, that is, it contains both sensory and motor fibers, present in mammals including humans in which it forms the seventh cranial nerve. Being a cranial nerve, it emits two fibers, one that runs on the right side of the face and the contralateral on the left. It starts of the brain stem, just between the brainstem and the medulla and controls the facial expression muscles, as well as the taste in the previous two thirds of the tongue. It also supplies parasympathetic preganglionic innervation to various nerve nodes in the head and neck.
