ANGIOLOGY 



1. The Superior Gluteal Veins (vv. glutaeoc superiores; gluteal veins) are vense 

 comitantes of the superior gluteal artery ; they receive tributaries from the buttock 

 corresponding with the branches of the artery, and enter the pelvis through the 

 greater sciatic foramen, above the Piriformis, and frequently unite before ending 

 in the hypogastric vein.

2. The Inferior Gluteal Veins (vv. glutaece inferior es; sciatic reins'), or vense comi- 

 tantes of the inferior gluteal artery, begin on the upper part of the back of the 

 thigh, where they anastomose with the medial femoral circumflex and first perfo- 

 rating veins. They enter the pelvis through the lower part of the greater sciatic 

 foramen and join to form a single stem which opens into the lower part of the hypo- 

 gastric vein. 



3. The Internal Pudendal Veins (internal pudic veins) are the vense comitantes 

 of the internal pudendal artery. They begin in the deep veins of the penis which 

 issue from the corpus cavernosum penis, accompany the internal pudendal artery, 

 and unite to form a single vessel, which ends in the hypogastric vein. They receive 

 the veins from the urethral bulb, and the perineal and inferior hemorrhoidal veins.
