Abducens nerve function involves moving which muscle?

Abducens nerve function involves moving which muscle?

• A. Medial rectus inward
• B. Superior rectus
• C. Inferior oblique
• D. Lateral rectus outward

Answer: (D)

The abducens nerve specializes in moving the eye outward by innervating the lateral rectus muscle. When the lateral rectus contracts, it pulls the eyeball toward the ear, producing abduction (outward movement). The other muscles listed are controlled by different nerves—primarily the oculomotor nerve—and have movements such as inward pulling (medial rectus) or upward/elevated or extorted actions, not the outward movement driven by the abducens. So the muscle associated with the abducens nerve is the lateral rectus, causing outward movement of the eye.
