WebThe neural folds, flanking the neural groove, converge and begin to meet midway of their lengths, thereby producing a neural tube at that level. Mesoderm, alongside the notochord, begins to subdivide into paired blocks called somites, and the outlines of the somites show externally. From them, muscles and vertebrae will differentiate later.
