When the somites split up, the cells of the sclerotome and the dermatome emigrate (Fig. 3–32, 9–5). Primordial germ cells, blood cells, and neural crest cells travel particularly long distances.

Cell Differentiation Frequently Is Irreversible and Causes Cell Death; Early Cell Death Can Be Prog terminally determined cells suddenly change their developmental program. In . (.) cells that have already undergone terminal differentiation undergo dedifferentiation and take new developmental pathways. Each of these phenomena are observed in the course of regenerative processes and will be discussed with examples in Chapter 21.

Still missing are the spinal ganglia and the essential parts of the autonomous nervous system, in particular, the sympathetic system and the peripheral components of the parasympathetic system, such as the neuronal network of the gut. These parts derive from the ..
