Globe: Sclera

Extrinsic ocular muscles consist of three three pairs of antagonistic muscles that control movement of the eye. They originate from the posterior region of the orbit and insert on the sclera. They A seventh muscle, the levator palpebrae, elevates the upper eyelid. All extraocular muscles are composed of skeletal muscle fibers that are innervated by cranial nerves III, IV and VI.
