The medial rectus muscle is a muscle in the orbit.
As with most of the muscles of the orbit, it is innervated by the inferior division of the oculomotor nerve (Cranial Nerve III).
This muscle shares an origin with several other extrinsic eye muscles, the anulus tendineus, or common tendon.
It is the largest of the extraocular muscles and its only action is adduction of the eyeball. Its function is to bring the pupil closer to the midline of the body. It is tested clinically by asking the patient to look medially.

- Medial rectus is one of the six extraocular muscles located in the orbit. Attaching between the bony walls of the orbit and the eyeball, these muscles serve to synchronously move the eyes. Besides medial rectus, this group of muscles also gathers the superior rectus , inferior rectus, lateral rectus, superior oblique and inferior oblique muscles.

- The medial rectus (also medial rectus muscle, medial rectus extraocular muscle, latin: musculus rectus medialis) is one of the six extra-ocular muscles that are in control of eye movements. Origin The medial rectus originates from the medial part of the common tendinous ring, and also from the dural sheath of the optic nerve.
