Question

Quizplus · Accepted Answer

Photopupillary and accommodation pupillary reflexes involve the cranial nerves that carry autonomic fibers. The photopupillary reflex involves the constriction of the pupil in response to light, and the accommodation reflex involves the constriction of the pupil when focusing on a near object. Both reflexes involve the oculomotor nerve (cranial nerve III), which carries parasympathetic fibers that innervate the muscles controlling pupil size.
