MEDIAL RECTUS Meaning and
Definition
-
The medial rectus is a term used in anatomy to refer to a specific muscle located in the eye. It is one of the six extraocular muscles responsible for controlling the movements of the eyeball. More specifically, the medial rectus muscle is located on the inner side of the eye and acts to move the eye towards the midline of the body. It is one of the two rectus muscles along with the lateral rectus muscle that work together to horizontally move the eye.
The medial rectus muscle is innervated by the oculomotor nerve, also known as cranial nerve III, which allows for the transmission of nerve signals between the muscle and the brain. When the brain sends signals to the medial rectus muscle to contract, it causes the eye to turn inward. This motion is referred to as adduction and is essential for maintaining proper eye alignment and convergence when focusing on near objects.
Disorders or dysfunction of the medial rectus muscle can lead to various eye conditions, such as strabismus (crossed eyes) or esotropia (inward deviation of the eye). These conditions may require medical intervention, including surgical correction of the muscle, to restore proper eye alignment and function.
