Fig. 1. Graphic reconstruction posterior cardinal veins of a 10 mm human embryo

Graphic reconstruction of right (A) and left (B) posterior cardinal veins of a 10 mm human embryo (no. 134 of Minnesota Collection). X 33.

Drawn from left side, to illustrate greater development of left veins (compare pls. 1 and 2 for orientation). Fus-., area of fusion between left and right blastemas; L. and R.'v.com., vena comitans of left and right umbilical arteries (each vein courses ventrolaterally to its respective umbilical artery until it reaches the caudal umbilical wall. There it anastomoses with the vein of the other side and with the umbilical veins.. These may be the veins which McClure and Butler designate in later stages as the “caudal mesonephric branches of the posterior cardinal veins”); P6..9, second portion of posterior cardinal vein; asterisk, designating level of vitelline artery; 12 and 17, lowest glomeruli of left and right Wolﬁan bodies, respectively (compare pl. 1).
