Question

The highlighted cranial nerve is the abducens nerve. Which of the following is an accurate description of this cranial nerve? a. It innervates the superior oblique muscle. b. It innervates the lateral rectus muscle. c. It innervates the lacrimal gland d. It innervates the medial rectus muscle.

Answer 1

b). it innervates the lateral rectus muscle.

Step-by-step explanation:

In neuroanatomy, the cranial nerve is characterized as any of the twelve paired nerves that originate from the brainstem or base of the brain instead of the spinal cord. These nerves are divided into three categories: sensory, motor, and the ones who perform both. The sensory cranial nerves allow humans to see things, hear sound, or smell things while motor cranial nerves control movements of the muscles of neck, as well as head. As per the given image, the second option most adequately elaborates this outlined cranial nerve that 'it propels the rectus muscle(that controls eyeballs' movement) of the side.' Thus, option b is the correct answer.
