This document provides information about 12 cranial nerves including their number, name, function, fiber type and innervation, and exit point from the skull. It lists each nerve's function as either sensory, motor, or both. It also categorizes fiber types for both motor and sensory fibers. The motor fibers are divided into general somatic efferent, special visceral efferent, and general visceral efferent. The sensory fibers are divided into general sensory afferent, general visceral afferent, and special sensory afferent.
