Question

Quizplus · Accepted Answer

The 3rd cranial nerve, also known as the oculomotor nerve, supplies motor innervation to most of the extraocular muscles, including the superior rectus, medial rectus, inferior rectus, and inferior oblique muscles, as well as the levator palpebrae superioris muscle. It also supplies parasympathetic fibers to the ciliary muscle and the sphincter pupillae muscle (which constricts the pupil). The superior oblique muscle, however, is innervated by the 4th cranial nerve (trochlear nerve), not the 3rd cranial nerve. The dilator pupillae, which dilates the pupil, is innervated by sympathetic fibers, not by the 3rd cranial nerve.
