The internal pudendal vein [v. pudenda interna] (fig. 536) begins at the termination of the 

 deep veins of tlie penis [\n' profundae penis] which issue from the corpus coavernosum penis with 

 the artery ot that body. These veins communicate with the dorsal vein at the root of the penis 

 In Its course the internal pudendal vem runs with the internal pudendal artery, receivine 

 tributaries corresponding to the branches of that vessel. It terminates in the lower part of the 

 hypogastric vein. ^
