Question

The oculomotor nerve __________.

Answer 1

Answer:

The correct answer is: a. directs somatic motor axons to four of the six extrinsic eye muscles and also transmits parasympathetic visceromotor impulses to pupillary constrictor muscle of the eye.

Explanation:

The oculomotor nerve (III) is the third cranial nerve. It provides motor innervation to four of the six extrinsic muscles of the eye and has also a parasympathetic component in charge of contracting the pupil when the environment is rich in light.

The cranial nerve that innervates the lateral rectus muscles of the eye is the abducens nerve (VI).

The cranial nerve that provides motor innervation to the superior oblique muscle of the eye is the trochlear nerve (IV).
