Fig. 12. A Graphic Reconstruction of the Umbilical Region of a Human Embryo 3 cm Long

(Mall collection, No. 86.)

The small sketch in the right upper corner indicates the points at which the sections of the cord have been made. This stage marks the maximal development of the exoccelom, the intestine completely filling its cavity. Section I, the nearest to the embryo, gives a frontal view of the narrow coelomic ring, which, on account of the solid tissue containing i he vascular structures below, appears in the form of a crescent. Emerging from the ring we see the small intestine to the right of the embryo, and the large intestine to the left, with the accompanying mesentery between them. In the cross-section of the mesentery are seen numerous sections of its arteries and vein. The omphalomesenteric vein passes outside of and above the mesentery; the omphalomesenteric artery comes from below, as seen in Section II. They soon leave the intestine and pass out into the funnel-shaped exocoelom.
