THE CIRCULATORY SYSTEM. 



The profunda femoris itself passes between the iliopsoas 

 and the pectineus muscles, then 

 to the medial surface of the 

 adductor femoris. It divides 

 into branches which supply 

 the pectineus, adductor / 

 longus, adductor femoris, 

 caudofemoralis, quadratus 

 femoris, semimembrano- 

 sus, and semitendinosus. 



2. A. femoralis (Fig. 

 127). This is the con- 

 tinuation of the external 

 iliac onto the medial sur- 

 face of the thigh. The 

 artery lies in a triangular 

 depression between the 

 borders of the sartorius ( 1 ) 

 and gracilis ( 9 ) muscles. The 

 floor of the depression is formed 

 by the adductor longus (6), pec- 

 tineus (5), vastus internus, and 



1 r^ 

 rectus femoris (s) muscles. This 



triangular depression is known as the ilio- 

 pectineal fossa, or Scarpa's triangle; it con- 

 tains also the femoral vein (a) and saphenous 

 nerve (), which pass along with the artery.
