EMULGENT VEINS. SPERMATIC VEINS. 325 



The Emulgent, or Renal Veins, 



Are very large vessels, and, like the arteries, go off nearly 

 at right-angles, one to each kidney. 



The right emulgent vein is not so long as the left, and it is 

 rather anterior to its corresponding artery. The left emulgent, 

 in its course to the kidney, crosses the aorta, and is anterior 

 to it. 



These veins pass to the sinus of each kidney, and ramify 

 before they enter it. The ramifications follow those of the 

 arteries. 



The Spermatic Veins 



Arise one on each side ; the right from the vena cava, and the 

 left from the emulgent vein. They proceed downwards behind 

 the peritoneum, and on the psoas muscle generally divide into 

 many branches, which communicate with each other as they 

 progress downwards, and form a plexus denominated Corpus 

 Pampiniforme. These branches proceed in the spermatic cord 

 to the back of the testis. The principal part enters the body of 

 that gland ; but some of the branches go to the epididymis. In 

 females the spermatic vein, like the artery, passes to the ovary, 

 the uterus and its appendages. 



The Lumbar Veins 



Correspond to the arteries of the same name. They arise 

 from the posterior and lateral parts of the inferior cava, and 

 those on the left side pass under the aorta. 



The Middle Sacral Vein 



Resembles the artery of the same name in its origin and 

 distribution. 



The Inferior Vena Cava accompanies the aorta to the space 

 between the fourth and fifth lumbar vertebrae, and there it also 

 divides into the two
