Fig. 11. Sagittal Section of the Umbilical Region in a Human Embryo 23 mm. in Length. The small drawing to the left, which is of natural size, accurately depicts the relation of the yolk-sac to the cord and amnion. Its stalk is very long, and the yolk-sac has become relatively smaller. The umbilical cord now shows very marked twisting. The exoccelomic cavity in the umbilical cord now contains practically all the intestine with the exception of the jejunum and descending colon. The distal portion of the cavity is funnel-shaped, the apex being directed away from the embryo. The omphalomesenteric duct has disappeared, but its vessels persist. The small cystic spaces in the upper wall of the cord mark the beginning obliteration of the exoccelom. The umbilical vein has been partly removed in order to bring into view the deeper structures. The two umbilical arteries, accompanied by the allantois, are in their usual position in the lower part of the cord. Note the slight spindle-shaped dilatation of the allantois in its course.
