Fig. 14. A Graphic Reconstruction of the Umbilical Region op a Human Embryo 4.5 cm in Length as viewed from within the abdomen
Coming from below are the two umbilical arteries with the urachus between them. Above is the umbilical vein, inclosed in a bulbous thickening of the surrounding tissue. The body-wall of the embryo at the cord has closed, save for an irregular slit. The exoccelom outside the general peritoneal cavity dilates, as indicated by the dotted line; it soon becomes obliterated. Plunging into the upper corner of the exoccelom, and adherent to its wall, are the omphalomesenteric vessels, accompanied by a thick cord of embryonic connective tissue, which, near the intestine, has an epithelial center but no lumen. This is undoubtedly a remnant of the omphalomesenteric duct. The section of the cord shown above is taken from near the embryo. It depicts the characteristic position of the allantois, and the narrow, slit-like termination of the exoccelom with the omphalomesenteric vein in its wall, the artery having disappeared.
