Cranial Nerve Ill:Oculomotor n. General somatic and visceral efferent fibers GSE extend from nucleus of oculomotor N.in midbrain,pass through the superior orbital fissure,and goes to the extra ocular muscles (levator palpebrae,superior rectus,inferior rectus,inferior oblique, medial rectus)except two(superior oblique and lateral rectus). GVE extend from accessory nucleus of oculomortor N.in midbrain,and goes to ciliary muscle and sphincter pupillae(parasympathic) via ciliary ganglia.• GSE extend from nucleus of oculomotor N. in midbrain, pass through the superior orbital fissure, and goes to the extra ocular muscles (levator palpebrae, superior rectus, inferior rectus, inferior oblique, medial rectus) except two (superior oblique and lateral rectus). • GVE extend from accessory nucleus of oculomortor N. in midbrain, and goes to ciliary muscle and sphincter pupillae (parasympathic) via ciliary ganglia.
