INFERIOR RECTUS Meaning and
Definition
-
The inferior rectus is a term used in human anatomy and specifically in the field of ophthalmology to refer to a muscle located within the eye. More specifically, it is one of the six extraocular muscles, responsible for controlling the movement and positioning of the eyeball. This muscle originates from a part of the eye socket known as the common tendinous ring and inserts into the sclera, which is the tough, white outer layer of the eye.
The primary function of the inferior rectus muscle is to rotate the eyeball downward and inward. In other words, it helps to move the eye towards the nose and downwards. This movement is crucial for tasks such as looking down, reading, or focusing on objects located close to the body.
The superior rectus muscle is located on the opposite side of the eye socket and has the opposite action of the inferior rectus. Together, these muscles work in a coordinated fashion to control the movement and positioning of the eyes.
In certain pathological conditions, such as strabismus (commonly known as crossed eyes), the inferior rectus muscle may not function properly, resulting in misalignment of the eyes. In such cases, medical intervention may be necessary to restore normal eye movement and ensure proper visual function.
