Lateral rectus muscle
- For the muscle of the neck, see Rectus capitis lateralis muscle
The lateral rectus muscle is a muscle in the orbit. It is one of six extraocular muscles that control the movements of the eye (abduction in this case) and the only muscle innervated by the abducens nerve, cranial nerve VI.
Its function is to bring the pupil away from the midline of the body. It is tested clinically by asking the patient to look laterally.
