Inferior oblique muscle
Inferior Oblique Muscle
The Inferior Oblique Muscle (pronunciation: In-fe-ri-or O-blique Mus-cle) is one of the extraocular muscles responsible for controlling the movements of the eye.
Etymology
The term "Inferior Oblique" is derived from Latin, where "Inferior" means lower and "Oblique" refers to a slanted or sloping direction.
Function
The primary function of the Inferior Oblique Muscle is to assist in the upward and outward movement of the eye. It is the only muscle, among the extraocular set, that is capable of elevating the eye when it is in an abducted position.
Anatomy
The Inferior Oblique Muscle originates from the orbital surface of the maxilla, and it inserts into the sclera, or the white part of the eye, behind the equator. This muscle is innervated by the oculomotor nerve (Cranial Nerve III).
