Which Extrinsic Eye Muscle is Innervated by the Abducens Nerve

Question

Which extrinsic eye muscle is innervated by the abducens nerve (CN VI)?
A)Inferior oblique
B)Superior oblique
C)Lateral rectus
D)Medial rectus
E)Superior rectus

Accepted Answer

The lateral rectus muscle is innervated by the abducens nerve (CN VI), which is responsible for abduction or outward movement of the eye. The medial rectus (innervated by the oculomotor nerve), superior rectus (innervated by the oculomotor nerve), inferior oblique (innervated by the oculomotor nerve), and superior oblique (innervated by the trochlear nerve) are all involved in different directions or movements of the eye.
