Detailed explanation-2: -Each oculomotor nerve innervates four of the six extrinsic muscles to move the eye, as well as the levator palpebrae superioris, which raises the upper eyelid. On either side of the brain, CN III emerges from the ventral midbrain surface to penetrate the posterior orbit wall, at the superior orbital fissures.
