Cranial nerve III (oculomotor) provides motor control and sensation for eye muscles and the upper eyelid. To determine the functioning of this nerve, the nurse would assess pupillary size and reaction to light. Cranial nerve II controls vision. Cranial nerve IV controls the movement of major eye muscles. Cranial nerve VI controls the movement and muscle sense of the eye.
