homology notes

We conclude this section by listing some of the many synapomorphies of craniates, including (...) (5) cranial nerves (...) (reference 1); Phylogenetically, the cranial nerves are thought to have evolved from dorsal and ventral nerves of a few anterior spinal nerves that became incorporated into the braincase. Dorsal and ventral nerves fuse in the trunk but not in the head, and they produce two series: dorsal cranial nerves (V, VII, IX, and X) and ventral cranial nerves (III, IV, VI, and XIII) (reference 2).[well established][VHOG]

taxon notes

the ophthalmic usually usually merges with the other two. In some vertebrates, the ophthalmic emerges from the brain separately[Kardong] The trigeminal nerve has 3 branches in mammals - similar branches are present in nonmammalian vertebrates, but in some a separate profundus nerve that corresponds to opthalmic branch in mammls
