Neuromuscular systems control the muscles within the eye (intraocular muscles); the muscles attached to the eye (extraocular muscles) and the muscles in the eyelid. There are a total of 12 cranial nerves (CN): Of these, CN I, CN II, CN VII, CN VIII, CN IX and CN X play roles in special sensory functions (i. olfaction, vision, gustation, audition, and balance); CN V (all three branches, the ophthalmic, maxillary, and mandibular) and CN IX play roles in. The oculomotor nerve is a cranial nerve pair that carries eye muscle command signals. When these nerves work properly, they help you see and contribute to many abilities. It provides motor and parasympathetic innervation to some of the structures within the bony orbit. The goal is to equip you with the knowledge you need to feel confident monitoring these patients and providing. The eyes are rotated by the action of six extraocular muscles, which act as three agonist/antagonist pairs allowing rotations in horizontal, vertical and torsional direc tions.
