(a–e) The central nervous system and associated systems of an adult lamprey (cyclostome), Ichthyomyzon bdellium, in left lateral view with (a) or without skeletal rendering (b), in dorsal view (c), and in ventral view with (d) and without associated structures (e). (f–j) The chondrocranium and associated systems of a bamboo shark (a crown gnathostome), Chiloscyllium plagiosum, in in left lateral view with (f) or without skeletal rendering (g), in dorsal view (h), and in ventral view with (i) and without (j) associated structures with semi-transparent skeletal rendering.
