editor note

classified as neural tree organ, not nerve in FMA. CN II poses a challenge here as it is not strictly a nerve, yet is expected to be classified under CN.

external definition

Twelve pairs of cranial nerves exit/enter the cranium through openings in the skull. The nerves contain efferent axons with motor and glandular functions, as well as afferent axons from cranial ganglia with sensory functions. The nerves are numbered in a rostral to caudal sequence, with the exception of the lateral line nerves.[TAO]
