The medial rectus is an extraocular muscle that attaches to the side of the eye near the nose. It moves the eye inward toward the nose. The lateral rectus is an extraocular muscle that attaches to the side of the eye near the temple..
Simply so, how do the eye muscles work?
For each eye, six muscles work together to control eye position and movement. Two extraocular muscles, the medial rectus and lateral rectus, work together to control horizontal eye movements (Figure 8.1, left). Contraction of the medial rectus pulls the eye towards the nose (adduction or medial movement).
Beside above, are eye muscles smooth or skeletal? The sphincter pupillae and dilator pupillae are also composed of smooth muscle. The medial rectus muscle is responsible for medial rotation around the vertical axis, and the lateral rectus lateral rotation. The superior rectus muscle primarily elevates the eye and contributes to adduction and intorsion.
Considering this, what are the six eye muscles?
