SUPERIOR RECTUS MUSCLE Meaning and
Definition
-
The superior rectus muscle is a muscle located in the orbit of the eye that is responsible for eye movement. It is one of the extraocular muscles, along with the inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique muscles.
The superior rectus muscle originates from the common tendinous ring, also known as the annulus of Zinn, at the back of the orbit. It then travels in a straight vertical path to attach to the sclera, which is the white outer surface of the eye, near the top of the eye's equator. This muscle functions to elevate the eye, causing it to look upward.
In terms of innervation, the superior rectus muscle is supplied by the oculomotor nerve (cranial nerve III). The oculomotor nerve consists of motor fibers that control the movement of multiple eye muscles, including the superior rectus.
In addition to its role in eye movement, the superior rectus muscle also plays a part in maintaining proper binocular vision. Binocular vision allows both eyes to work together, aiding in depth perception and the ability to judge distances accurately. The coordinated action of the superior rectus muscle with the other extraocular muscles allows for smooth and precise eye movements.
