oculomotor
Third cranial nerve
Oculomotor refers to the movement of the eye.
The oculomotor nerve, the third cranial nerve, controls most of the muscles that move the eyeball, raise the eyelid, and constrict the pupil.
The term appears mainly in medical and anatomical contexts: oculomotor dysfunction, oculomotor control.
