    extrinsic eye muscles that are primarily responsible for eye movement.” The three nerves that contribute to human eye movement are: oculomotor, abducens and trochlear nerve. The oculomotor is a pure motor nerve, “that controls the superior, inferior and medial rectus,” (Marieb, 495) The abducens nerve is a purely motor nerve that carries motor impulses to the lateral rectus that permits the eye to move side to side and abduct. The trochlear nerve innervates the superior oblique eye muscle that allows
