abducens
n. C1 Advanced ab·ducens
n. a nerve in the body that helps you move your eye to the side. It is one of the nerves that controls how your eyes work together.
n. the sixth cranial nerve, responsible for the lateral rectus muscle of the eye, which controls abduction of the eyeball. It is the only cranial nerve that innervates a muscle of the eye that moves it laterally.
The doctor checked the abducens nerve to see if the eye moved correctly.
Damage to the abducens nerve can cause the eye to turn inward, making it difficult to look sideways.
The patient's inability to abduct the right eye suggested a lesion in the abducens nerve, which is located in the brainstem and is vulnerable to various neurological insults.
