What are the 12 cranial nerves?

The 12 cranial nerves are a set of nerves that emerge directly from the brain and are responsible for facilitating various essential functions in the body. These nerves are named according to their assigned Roman numerals, and they serve diverse functions such as carrying sensory information from the head and neck, controlling movements of the eye, regulating facial expressions, facilitating hearing and speech, assisting in swallowing, and controlling the overall functioning of the autonomic nervous system. Understanding each of the 12 cranial nerves is essential in diagnosing and treating neurological disorders and injuries that can affect the healthy functioning of these nerves.
