(5) cranial nerves (...).[well established][VHOG] UBERON:0001785 uberon UMLS:C1269897 NCIT:C12700 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] cranial neural tree organ UMLS:C0010268 GAID:802 cranial nerves EHDAA2:0000323 neuronames:1227 AAO:0000108 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. FMA:5865 BTO:0001104 TAO:0000641 ZFA:0000641 VHOG:0000279 MA:0000215 Cranial nerves are nerves that emerge directly from the brain, in contrast to spinal nerves, which emerge from segments of the spinal cord.
