Fig. 8. Sagittal View of the Umbilical Region of a Human Embryo 10 mm in Length
The yolk-sac now lies far removed from the umbilical cord; its vessels and stalk follow a tortuous course. The umbilical cord here shows the first indication of a twist, which may be caused by the embryo rotating toward the right. In the embryos examined by us there has been but one exception to this rule. The small intestine extends a considerable distance into the exocoelom of the cord. At the outer end of the intestinal loop is situated the delicate omphalomesenteric duct. The omphalomesenteric vein passes on the left side of the intestinal loop; the artery, on the right side.
