| ||The sequence '''neural plate to neural groove to neural tube''' represents the gradual folding of a flat surface sheet of ectodermal cells into a closed tube isolated from the embryo surface. The '''notochord''' is part of the mesoderm and regulates the initial overlying differentiation process. The '''neural crest''' are a population at the edge of the neural plate that do not get incorporated into the neural tube. I think I made up '''neural zone'''.
