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] UBERON:0001785 UMLS:C0010268 UMLS:C1269897 VHOG:0000279 We conclude this section by listing some of the many synapomorphies of craniates, including (...)
