The extrinsic eye muscles are innervated by cranial nerves III (oculomotor), IV (trochlear), and VI (abducens). Specifically, the oculomotor nerve innervates the superior rectus, inferior rectus, and medial rectus muscles, while the trochlear nerve innervates the superior oblique muscle and the abducens nerve innervates the lateral rectus muscle.
