Cranial nerves are nerves that emerge directly from the brain, in contrast to spinal nerves, which emerge from segments of the spinal cord. [ http://en.wikipedia.org/wiki/Cranial_nerve ]
Synonyms: cranial neural tree organ

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]
We conclude this section by listing some of the many synapomorphies of craniates, including (...) (5) cranial nerves (...).[well established][VHOG]

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.
