Expansion of prospective neural plate and growth of notochord from the node in the schematic dorsal view of rabbit embryo. a prior to the notochord formation (stage 4), b early notochord stage (stage 5). Labeling: arrows—growth of the blastoderm, dotted arrow—direction of notochord growth, red—notochord, pink—primitive streak, black—primitive groove
