Oblique Muscle

Either of two muscles, the superior oblique (a long thin muscle that arises just above the margin of the optic foramen, is inserted on the upper part of the eyeball, and moves the eye downward and rotates the top of the eye nasally) or the inferior oblique (a short muscle that arises from the orbital surface of the maxilla, is inserted slightly in front of and below the superior oblique, and moves the eye upward and rotates the top of the eye temporally).
