LATERAL RECTUS Meaning and
Definition
-
The lateral rectus is a term used in anatomy to describe one of the six extraocular muscles found in each eye. It is specifically referred to as the lateral rectus muscle. The lateral rectus muscle is responsible for the lateral movement of the eyeball away from the midline of the body, or in other words, towards the side of the head. This muscle acts in opposition to the medial rectus muscle, which is responsible for medial movement of the eyeball towards the midline.
The lateral rectus muscle is innervated by the abducens nerve (CN VI), which is essential for its contraction and control. It arises from the annulus of Zinn, a fibrous ring located at the back of the orbit (eye socket), and travels laterally along the eye, attaching to the outer surface of the eye near the lateral canthus.
Any dysfunction or abnormality of the lateral rectus muscle can result in an impairment or deviation of the eye's movement. For instance, weakness or paralysis of the lateral rectus muscle may lead to an inability to move the eye laterally, a condition referred to as lateral rectus palsy. This can result in double vision or strabismus, where both eyes are not properly aligned. Treatment for such conditions may involve eye exercises, prisms, or in severe cases, surgical interventions.
