Question

what are the functions of the oculomotor nerve (cn iii)? it controls muscles that raise the eyelid. it carries sensory impulses for the sense of vision. it carries sensation from the skin of the face. it controls muscles of the pupil, to adjust the amount of light entering the eye. it controls muscles that move the eye.

Explanation:

The oculomotor nerve (CN III) is a motor - nerve. It innervates the levator palpebrae superioris muscle which raises the eyelid. It also supplies parasympathetic fibers to the ciliary muscles (for accommodation) and the sphincter pupillae (to constrict the pupil). Additionally, it innervates several extra - ocular muscles that move the eye. The sense of vision is carried by the optic nerve (CN II), and sensation from the face is carried by the trigeminal nerve (CN V).

Answer:

• It controls muscles that raise the eyelid.
• It controls muscles of the pupil, to adjust the amount of light entering the eye.
