the two parts of the suspensory ligament and then through an aperture between 

 the subpubic ligament and the apex of the triangular ligament, and divides into 

 two branches, which enter the vesicoprostatic plexus. The dorsal vein of the 



clitoris corresponds in woman to 

 the dorsal vein of the penis in man, 

 and empties into the inferior vesical 

 plexus. 



The Vaginal Plexuses and Veins 

 (Fig. 526). The vaginal plexuses 

 are placed at the sides of the 

 vagina, being especially developed 

 at the orifice of the canal. They 

 receive vessels from the vaginal 

 w r alls. The plexuses communicate 

 with the uterine plexus above, with 

 the bulbar veins below, with the 

 inferior vesical plexus in front, and 

 with the hemorrhoidal plexus be- 

 hind, and are drained by the vaginal veins, one on either side, into the internal 

 iliac veins. 



The Uterine plexuses (Fig. 526) are situated along the sides and superior angles 

 of the uterus, between the two layers of the broad ligament, and communicate 

 with the ovarian and vaginal plexuses. They are drained by the uterine veins

(m>. uterinae) (Fig. 526) which arise from the lower part of the plexus. There 

 are usually two veins on each side, and they are not provided with valves. These 

 veins for the first portion of their course are placed in the base and inner portion 

 of the broad ligament; they then pass back with the uterine artery and terminate 

 in the internal iliac vein. 



During pregnancy the uterine veins become greatly enlarged. 



The common iliac veins (Figs. 522 and 524) are formed by the union of the 

 external and internal iliac veins in front of the sacroiliac articulation; passing 

 obliquely upward toward the right side, each vein terminates upon the interverte- 

 bral substance between the fourth and fifth lumbar vertebrae, where the veins of
