[Continued from above] . . . downward and toward the midline, (3) medial rectus, - rotates the eye toward the midline, (4) lateral rectus, - rotates the eye away from the midline, (5) superior oblique, - rotates the eye downward and away from the midline, and (6) the inferior oblique - rotates the eye upward and away from the midline. There are two check ligaments (the lateral and medial check ligaments), which limit the movement of the lateral and medial rectus. The motor units of these eye muscles contain the smallest number of muscle fibers (5-10) of any muscle in the body. Because of this, the eyes move together so that they are aligned when looking at something. A person whose eyes are not coordinated well enough to produce this alignment is said to have strabismus, or squint.
