development_notes	The human trochlear nerve is derived from the basal plate of the embryonic midbrain.
taxon_notes	Homologous trochlear nerves are found in all jawed vertebrates
external_definition	Somatic efferent nerve which supplies a single eye muscle, the m. obliquus superior.[AAO]
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]
