CHAPTER II THE NEURAL TUBE AND ITS DERIVATIVES Infolding of the Neural Tube.— The vertebrate nervous system developsfrom a thickened plate of ectoderm along the middorsal line of the the infolding of this neural plate there is formed the neural groove, whichbecomes transformed into the neural tube (Fig. 6). The neural tube detachesitself from the superficial ectoderm and gives rise through a thickening of itswalls to the brain and spinal cord. The latter is formed by a process of uniform Neural groove Neural plate Neural groove Neural plate. Ectoderm Neural groove
