All of the Following Cranial Nerves Innervate the Extrinsic Eye

Question

All of the following cranial nerves innervate the extrinsic eye muscles except
A)the facial nerve.
B)the abducens nerve.
C)the trochlear nerve.
D)the oculomotor nerve.
E)all of these cranial nerves innervate the extrinsic eye muscles.

Accepted Answer

The facial nerve does not innervate any of the extrinsic eye muscles. The oculomotor nerve innervates the superior rectus, inferior rectus, medial rectus, and inferior oblique muscles, while the trochlear nerve innervates the superior oblique muscle, and the abducens nerve innervates the lateral rectus muscle. Therefore, options B, C, and D are incorrect as they all innervate extrinsic eye muscles.
