THE ARTERIES 



is superficial to it, InU is se])arated from this part of the femoral artery by 

 the (lee|) fasria. 



Behind, the artery lies on the peetincus, from wliicli it is separated by the 

 femoral vein and the profunda vein and artery. Lower down, it lies on the upper 

 portion of the adductor longus muscle. 



To its outer side is tlie long saphenous nerve and the nerve to the vastus internus, 

 the anterior crural nerve having in this situation more or less broken up into its 

 components.

To its inner side is the femoral vein, which, however, at the apex of Scarpa's 

 triangle, is getting somewhat behind the artery. 



The superficial femoral varies in length according to the distance that the pro- 

 funda is given off from the common femoral below Poupart's ligament. As a rule, 

 it measures three inches and a half (9 cm. ), the commim an inch and a half (4 cm. ). 

 Hut the profunda may come off two or more inches below Poupart's ligament, in 

 which case the superficial femoral will be shorter to this extent; or it may come off 

 less than an inch and a half below Pcnipart's ligament, or even from the external 

 iliac a1)0ve Poupart's ligament, wlicn the superficial will be longer tlian normal. The
