			The anterior cardinal veins (Figs. 374 and 375) are formed to drain the plexus of veins on each side of the head. These vessels extend caudad and lie ventro-lateral to the myelencephalon. Each receives branches from the sides of the myelencephalon, then curves ventrad, is joined by the linguo-facial vein from the branchial arches and at once unites with the posterior cardinal of the same side to form the common cardinal vein. This, as already explained, opens into the sinus venosus.

	A posterior cardinal vein develops dorso-lateral to each mesonephros (Figs. 374 and 375). Running cephalad, they join the anterior cardinal veins. When the mesonephroi become prominent, as at this stage, the middle third of each posterior cardinal is broken up into sinusoids. Sinusoids extend from the posterior cardinal vein ventrally around both the lateral and medial surfaces of the mesonephros. The median sinusoids anastomose longitudinally and form the subcardinal veins, right and left.		A posterior cardinal vein develops dorso-lateral to each mesonephros (Figs. 374 and 375).
