Cranial nerve number designating the facial nerve?

Explanation:
Cranial nerve numbering designates the facial nerve as VII. The facial nerve is the seventh cranial nerve, and it innervates the facial muscles used for expression plus parasympathetic fibers to some glands, with sensory roles such as taste from the anterior part of the tongue via its branches. In this system, other numbers point to different nerves: II is the optic nerve for vision, X is the vagus nerve with widespread autonomic functions, and III is the oculomotor nerve that controls most eye movements. So the facial nerve’s designation is VII.
