They change little during the course of evolution.[well established][VHOG] VHOG:0001128 TAO:0000345 SCTID:181153003 m. rectus superior UBERON:0006323 MA:0001282 dorsal rectus 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. rectus extraocular muscle
