252 PRACTICAL ANATOMY. 



anterior wall of the abdomen, perforates the sheath of 

 the rectus, which it supplies, and anastomoses with the 

 descending branch of the internal mammery. It sends 

 off branches to spermatic cord, to the pubes, and to the 

 muscles. Sometimes it arises in common with the 

 obturator. 



Deep Circumflex. Runs upward and outward be- 

 tween the transversalis and the internal oblique, close 

 to the crest of the ilium. It supplies the muscles of the 

 outer and anterior part of abdomen. 



THE FEMORAL ARTERY. 



The femoral artery is a continuation of the external 

 iliac. It passes beneath Poupart's ligament midway be- 

 tween the anterior superior spinous process and the spine 

 of the pubes; a line drawn from this point to the inner 

 side of the internal condyle of the femur will overlie the 

 artery. It sends off the following branches : 



Superficial Epigastric. Arises from the femoral 

 artery half an inch below Poupart's ligament, passes 

 upward and inward, and supplies the integument of 

 the abdomen. 



Superficial Circumflex Iliac. Comes off opposite to 

 the superficial epigastric, passes upward and outward, 

 and is distributed to the integument of the abdomen. 



Superficial External Pudic. Supplies integument of 

 inner side of groin, the scrotum, and integument of penis. 



Deep External Pudic. Supplies the skin of peri- 

 neum and scrotum and muscles. 



Prof unda. Almost as large as the femoral ; it passes 

 down deeply and sends off (a) the External Circumflex, 

 supplies the structures on anterior and outer part of the 

 thigh ; (6) the Internal Circumflex, supplies the struc- 

 tures on anterior and inner part of the thigh ; these ves-
