Oculomotor Nerve

Medical Definition:	The 3d cranial nerve. The oculomotor nerve sends motor fibers to the levator muscles of the eyelid and to the superior rectus, inferior rectus, and inferior oblique muscles of the eye. It also sends parasympathetic efferents (via the ciliary ganglion) to the muscles controlling pupillary constriction and accommodation. The motor fibers originate in the oculomotor nuclei of the midbrain.
Guide Notes:	neopl = OCULOMOTOR NERVE DISEASES (IM) + CRANIAL NERVE NEOPLASMS (IM) + histol type of neopl (IM)
