'''Lateral rectus muscle''' is one of the six [[extraocular muscles]] that control the movements of the eye. It is the only muscle that is responsible for [[abduction]] of the eye, which is the movement of the eye away from the midline of the body.

== Anatomy ==
The lateral rectus muscle originates at the [[annulus of Zinn]], also known as the common tendinous ring, which is located at the apex of the [[orbit (anatomy)|orbit]]. From there, it extends laterally to the [[temporal bone|temporal]] side of the eyeball. The muscle is innervated by the [[abducens nerve]], also known as the sixth cranial nerve.

== Function ==
The primary function of the lateral rectus muscle is to pull the eyeball laterally, away from the midline of the body. This action is known as abduction. The muscle works in conjunction with the [[medial rectus muscle]], which pulls the eyeball medially, towards the midline of the body.

== Clinical significance ==
Damage to the lateral rectus muscle or its nerve supply can result in a condition known as [[abducens nerve palsy]], which is characterized by an inability to turn the eye outward. This can result in [[diplopia]], or double vision. Treatment for this condition may involve surgery to reposition the muscle or to weaken the opposing medial rectus muscle.
