Scheme of arrangement of parietal veins

FIG. 477– Scheme of arrangement of parietal veins.

The Parietal Veins

The first indication of a parietal system consists in the appearance of two short transverse veins, the ducts of Cuvier, which open, one on either side, into the sinus venosus. Each of these ducts receives an ascending and descending vein. The ascending veins return the blood from the parietes of the trunk and from the Wolffian bodies, and are called cardinal veins. The descending veins return the blood from the head, and are called primitive jugular veins (Fig. 477).
