Detailed explanation-1: -The oculomotor nerve controls several muscles: Levator palpebrae superioris-raises the upper eyelid. Superior rectus muscle-rotates the eyeball backward, “looking up” Medial rectus muscle-adducts the eye, “looking towards your nose"
Detailed explanation-2: -The facial or seventh nerve innervates the circumferential orbicularis oculi to close the upper and lower eyelids. The oculomotor or third cranial nerve innervates the levator palpebrae superioris to elevate the upper eyelid.
Detailed explanation-3: -Three of these cranial nerves, cranial nerve III (3), cranial nerve IV (4) and cranial nerve VI (6) are responsible for all of the eye’s movements. Problems with these nerves can cause issues with eye position and movement including eyes turning in, turning out, or being vertically misaligned or causing double vision.
