Medial rectus
Medial Rectus
The Medial Rectus (pronounced: MEE-dee-uhl REK-tuhs) is one of the six Extraocular muscles that control the movements of the eye. Its primary function is to rotate the eye towards the nose, a movement known as adduction.
Etymology
The term 'Medial Rectus' is derived from Latin, where 'medialis' means 'middle' and 'rectus' means 'straight'. This is in reference to the muscle's position and function in the eye.
Function
The Medial Rectus muscle, like the other extraocular muscles, is controlled by the Oculomotor nerve. It is primarily responsible for moving the eye inward towards the nose, a movement known as adduction. This muscle plays a crucial role in Convergent strabismus, where one or both eyes turn inward.
