ARTERIES 91 



wall, as high as umbilicus, in the fascia, anas, fellow of 

 opposite side, superficial branches of deep epigastric. 



Superficial circnmflex iliac : arises near preceding, runs 

 outwards to iliac crest, supplies glands, fasciae, and integu- 

 ment, psoas and iliacus; anas, deep circumflex iliac, gluteal, 

 external circumflex. 



Superior external pudic : arises from inner side of artery 

 ^ inch below Poupart's ligament, pierces cribriform fascia of 

 saphenous opening, runs upwards to pubic spine, crosses ex- 

 ternal ring and spermatic cord, supplying integument of lower 

 part of abdomen and external organs of generation ; anas, in- 

 ternal pudic. 



Deep external pudic : arises either separately or from a 

 common trunk with the preceding, lies on pectineus, covered 

 by fascia lata, which it pierces, and is distributed to scrotum 

 in male and labium in female ; anas, superficial perineal. 



Profunda femoris : arises from outer and back part of artery, 

 i or 2 inches below Poupart's ligament, and passing outwards 

 and downwards rests in Scarpa's triangle upon the iliacus, 

 then curving inwards, crosses psoas and pectineus behind the 

 femoral artery, from which it is separated by the deep femoral 

 vein , and lies subsequently upon adductores brevis and magnus, 

 having the longus superficial to it. It ends in the lower third 

 of thigh in a branch which perforates adductor magnus. 



Brandies : 



External circumflex : arises from the outer side of the pro- 

 funda (sometimes from the femoral trunk), coursing under 

 rectus and sartorius outwards through the divisions of the 

 anterior crural nerve, dividing into : 



(a) Transverse branches, piercing vastus externus just below 

 great trochanter; anas, below trochanter with internal circum- 

 flex, first perforating branch of profunda, and sciatic, (crucial 

 anastomosis). 



(b) Ascending pass beneath sartorius, rectus, and tensor 

 fasciae femoris ; anas, with terminal of gluteal and deep 

 circumflex iliac. 



(c) Descending branches are distributed to the extensors of 

 the thigh ; anas, with superior articular arteries, a small offset 

 passing, with the articular nerve from the nerve to vastus ex- 

 ternus, to the knee-joint. 



Internal circumflex : arises from the internal and back part 

 of profunda, courses backwards between psoas and pectineus, 

 and then below capsule of hip between obturator externus 

 and adductor brevis, dividing at the small trochanter into 

 two branches, one ascending deep to quadratus femoris to
