Anatomical terms of muscle [edit on Wikidata]

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 superior rectus muscles is shown in this image of the right eye from above. Hover the mouse over the structures for their names. Click for more information.

Structure

Function

See also: Eye movement

It elevates, adducts, and helps intort (rotate medially) the eye.

Clinical significance

Testing

The superior rectus muscle is the only muscle that is capable of elevating the pupil when it is in a fully abducted position.
