The nervous system develops from the ectoderm germ layer as a flat sheet
forms called the neural plate. This plate invaginatesto form the neural
groove. Offshoots of this plate called the neural folds develop into neural
crest cells which form most of the PNS, while the neural groove
completely encloses to form a neural tube which becomes the CNS...
