MEDIAL RECTUS MUSCLE Meaning and
Definition
-
The medial rectus muscle is a large muscle located within the eye socket, specifically in the orbit region. It is one of the six extrinsic muscles that control the movement of the eyeball. It arises from the common tendinous ring, also known as the annulus of Zinn, and has its origin at the apex of the orbit. The muscle extends towards the front of the eye where it attaches to the sclera, known as the white part of the eye, near the cornea.
The primary function of the medial rectus muscle is to control the horizontal movement of the eyeball inward. When both medial rectus muscles contract simultaneously, they facilitate convergence, allowing the eyes to turn inward to focus on objects close to the face, as in reading or observing something up close.
In addition to its primary role in eye movement, the medial rectus muscle also plays a crucial part in maintaining binocular vision and depth perception. It works in conjunction with the other extrinsic eye muscles to ensure coordinated eye movements and alignment, contributing to the overall function of the visual system.
Damage or impairment to the medial rectus muscle can result in a variety of conditions such as strabismus, a condition commonly referred to as crossed eyes, or diplopia, also known as double vision. Treatment may involve exercises, glasses, or surgery depending on the severity and underlying cause of the condition.
