Definition

Cranial nerves serve as conduits for communication between the brain and the body, providing motor and sensory innervation to structures in the head and neck as well as the thoracic and abdominal viscera. There are 12 pairs of cranial nerves, each of which is designated by both a Roman numeral and a name (see Table 1). Roman numerals I–XII indicate the rostrocaudal order in which cranial nerves emerge from the brain, while the name designated to each pair of cranial nerves denotes either its function or distribution.
