Preferred Label : medial rectus extraocular muscle;
Uberon definition : 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. [WP,unvetted].;
Uberon synonym : medial rectus; m. rectus medialis; musculus rectus medialis; medial rectus muscle;
Uberon related term : medial recti;
Uberon Homology note : The ability to rotate the eyeball is common to all vertebrates with well-developed
eyes, regardless of the habitat in which they live, so these [extrinsic ocular] muscles
tend to be conservative. They change little during the course of evolution.[well established][VHOG];
