VEINS OF THE ABDOMEN. 267 



perficial veins of the penis and of the scrotum, and disengaging 

 themselves from the tunica vaginalis, at its back part, are assem- 

 bled into four or five anastomosing trunks; which envelop the 

 vas deferens and the spermatic artery, and compose a principal 

 part of the bulk of the chord. Having passed through the ab- 

 dominal canal, they are reduced on each side to one trunk, 

 which creeps along the spermatic artery on the front of the 

 psoas magnus muscle, and in company with the ureter. Some- 

 what below the kidney, the spermatic vein is again resolved 

 into a sort of plexus, having frequent additions from the veins, 

 in the adipose substance of the kidney, and also some from the 

 branches of the vena portarum in the mesentery, and in the 

 mesocolon. It then is reduced o-nce- more into a single trunk, 

 which terminates as mentioned. The terra Corpus Pampini- 

 forme (vine-like) is, by some anatomists, limited to the last 

 plexus formed by each spermatic vein, but it is also frequently 

 extended to both.* 



In the female, the spermatic vein is not so large as in the 

 male; it comes from the ovarium and from the side of the 

 uterus, and is joined by some small branches from the round 

 ligament of the uterus, and from the Fallopian tube. Passing 

 outwardly between the laminae of the broad ligament of the 

 uterus, it crosses the external iliac artery, and in the subsequent 

 part of its course is disposed of as in the male. 



The Emulgent Veins (Ven<z Emulgentes^ Renaks) are com- 

 monly two in number, one on each side, and extend horizon- 

 tally from the fissure of the kidneys to the ascending cava. 

 They are of a considerable size, and owing to the position of 

 the vena cava, the left is much longer than the right, and 

 crosses in front of the aorta. They open on their respective 

 sides of the cava opposite to each other. The branches of 

 which the emulgent vein is composed, coming from the rami- 

 fications of the corresponding artery in the kidney, assemble 

 into the single trunk near the fissure of the kidney; this 

 trunk is joined by some small veins from the adjacent adi- 

 pose matter and from the capsulae remles, and on the left 

 side, as mentioned, it is also joined by the spermatic vein.
