Final answer:

The optic nerve does not control eye movement. The extraocular muscles are controlled by the oculomotor, trochlear, and abducens cranial nerves.

Step-by-step explanation:

The extraocular muscles are controlled by three cranial nerves: oculomotor, trochlear, and abducens. The optic nerve is responsible for transmitting visual information from the eye to the brain and does not control eye movement. The oculomotor nerve controls most of the other extraocular muscles and a muscle of the upper eyelid. The trochlear nerve innervates the superior oblique muscle, and the abducens nerve controls the lateral rectus muscle.
