Question

Explanation:

The oculomotor nerve (CN III) innervates several extra - ocular muscles (superior rectus, medial rectus, inferior rectus, inferior oblique) that are responsible for adduction, elevation, and depression of the eye. In a complete oculomotor nerve palsy, all the functions of the muscles it innervates are lost.
