Plate 1.

1. The design of the actual embryonic body begins with a stage, as shown him in the standard panel Figure I shows us. In a relatively large yolk sac lies flat spread the germ shield with primitive streak and neurenteric canal, in front of the neurenteric canal a shallow medullary groove expands, which is flanked by shallow, not sharply defined medulla bulges. (p84)
3. The emergence of the brain part relative to the spinal cord part of the central nervous system makes early claims. Even in an embryo, 6-7 mesoblastic somite pairs (standard panel Figure III) are the three primary brain divisions are distinguishable and the cephalic flexure has occurred. (p84)
4. In the Figs. IV and V of the standard panel the cranial and caudal medullary tube is still open.
5. In the Figs. IV and V of the standard panel the cranial and caudal medullary tube is still open.
6. The neural tube closes initially at the cranial end; on the embryo which is shown in Figure VI of the standard panel, the closing position of the front neuropore can be seen more precisely; (p84)
7. In the embryo of Figure VII the posterior neuropore very close to the end. The caudal end of the medullary system does not result from the formation and closure of medullary fold, but differentiates itself with notochord and tail gut can call from the indifferent cell mass, which we see arise at the caudal embryonic end after shrinkage of the primitive streak and the tail bud. (p85)
10. The peak of the curvature is seen in the embryos of Figs. X and XI of the standard panel. Now the body begins to stretch, perhaps under the influence of himself more and more from the forming liver, which is also reflected in the surface image under the cardiac prominence more and more claims and this probably holds the balance in Figure XIV.
