of the Spermatic artery. The deferential artery is sometimes of 

 large size, and then it takes the place of the spermatic artery when 

 that vessel is absent. 



The deferential vein opens into the vesical plexus of veins, and 

 thence into the internal iliac vein. 



The spermatic artery arises from the abdominal aorta about 

 I inch below the renal artery. On approaching the upper part 

 of the testis it divides into testicular and epididymal branches, the 

 former supplying the testis and the latter the epididymis. As

the artery descends in the spermatic cord it supplies branches to 

 its coverings which anastomose with the cremasteric artery, and 

 its epididymal branches anastomose with the deferential artery. 



For the cremasteric artery, see p. 662. 



The spermatic veins issue from the testis along its posterior 

 border. In the cord they form a copious ple.xus, called the 

 pampiniform plexus. At the internal abdominal ring two veins 

 emerge from this plexus, which range themselves on either side 

 of the spermatic artery. These, as they ascend, soon join to 

 form one vessel, that of the right side opening into the inferior vena 

 cava, and that of the left side into the left renal vein. The veins of
