Cranial Nerves

Cranial nerve pairs

The brain is the main structure of the nervous system. It is located in the anterior and superior part of the cranial cavity and is present in all vertebrates. It communicates constantly with the rest of the body through the sense organs.

The cranial nerves consist of 12 pair of nerves originating directly from the brain and brainstem. They supply both motor and sensory information from the brain to other parts of the body, primarily supplying the region of the head and neck.
