Superior rectus muscle

The superior rectus muscle is a muscle in the orbit. It is one of the extraocular muscles. It is innervated by the superior division of the oculomotor nerve (Cranial Nerve III). In the primary position (looking straight ahead), the superior rectus muscle's primary function is elevation, although it also contributes to intorsion and adduction.The right eye in sagittal section, showing the fascia bulbi (semidiagrammatic).Superior rectus muscleSuperior rectus muscleExtrinsic eye muscle.

It is innervated by the superior division of the oculomotor nerve (Cranial Nerve III). In the primary position (looking straight ahead), the superior rectus muscle's primary function is elevation, although it also contributes to intorsion and adduction. It elevates, adducts, and helps intort (rotate medially) the eye. The superior rectus muscle is the only muscle that is capable of elevating the eye when it is in a fully abducted position.
