Oculomotor n

CN III, the oculomotor n. provides motor innervation to 4 of the 6 extrinsic eye muscles (NOT the superior oblique or lateral rectus) and the levator palpebrae superioris, and parasympathetic innervation to the ciliary m and constrictor pupillae m.  The oculomotor n. passes through the superior orbital fissure to exit the cranial cavity and enter the orbit.
