Morphology of the trigeminal nerve. a Whole-mount immunofluorescence for the Arctic lamprey (L. camtschaticum) prolarva at st. 27. Peripheral nerves are visualized by an anti-acetylated tubulin antibody in green and cell nuclei are labeled DAPI in blue. b Schematic illustration of the cranial nerves. c Whole-mount immunofluorescence for the catshark (S. torazame) embryo at st. 27. Peripheral nerves are visualized by an anti-acetylated tubulin antibody in magenta, and cell nuclei are labeled by DAPI in blue. d Schematic illustration of the cranial nerves. e, f Another catshark embryo (st. 30) for detailed microscopy. Peripheral nerves are visualized by an anti-acetylated tubulin antibody in green. The overview of the ventral head regions is shown in (e). The magnified oral region is shown in (f), observed from a slightly ventral aspect. Scale bars: 100 μm for (a), 1 mm for (c), and 1 mm for (d)
