(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] trochlear nerve tree BAMS:nIV trochlear nerve [IV] nervus trochlearis fourth cranial nerve AAO:0010469 trochlear IV nerve GAID:838 UMLS:C0041159 CN-IV nerve IV FMA:50865 trochlear nerve EHDAA2:0002090 trochlear nerve or its root trochlear nerve/root HBA:9319 cranial nerve IV A cranial nerve that runs to the eye muscles. pathetic nerve neuronames:466 uberon MBA:911 Somatic efferent nerve which supplies a single eye muscle, the m. obliquus superior.[AAO] The human trochlear nerve is derived from the basal plate of the embryonic midbrain.
