Superior rectus
Superior Rectus
The Superior Rectus (pronunciation: su·pe·ri·or rec·tus) is one of the extraocular muscles that control the movements of the eye. It is responsible for upward rotation of the eye.
Etymology
The term "Superior Rectus" is derived from Latin, where "superior" means upper and "rectus" means straight. This is in reference to the muscle's position and function in the eye.
Function
The Superior Rectus muscle is innervated by the oculomotor nerve (Cranial Nerve III). It primarily moves the eye upward but also contributes to inward rotation and adduction (movement towards the midline of the body).
