FEMORAL.

extends transversely from the Vastus Internus to the tendons of the Adductor 

 Longus and Adductor Magnus muscles. In this part of its course it lies in a 

 depression, bounded exter- 

 nally by the Vastus Internus, Fig. 298. Surgical Anatomy of the Femoral Artery, 

 internally by the Adductor 

 Longus and Adductor Mag- 

 nus. The femoral vein lies 

 on the outer side of the arte- 

 ry, in close apposition with 

 it, and, still more externally, 

 is the internal (long) saphe- 

 nous nerve. 



Relations. From above down- 

 wards, the femoral artery 

 rests upon the Psoas muscle, 

 which separates it from the 

 margin of the pelvis and cap- 

 sular ligament of the hip ; it 

 is next separated from the 

 Pectineus by the profunda 

 vessels and femoral vein ; it 

 then lies upon the Adductor 

 Longus ; and lastly, upon the 

 tendon of the Adductor Mag- 

 nus, the femoral being inter- 

 posed. To its inner side, it is 

 in relation above, with the fe- 

 moral vein, and, lower down, 

 with the Adductor Longus, 

 and Sartorius. To its outer 

 side, the Vastus Internus sepa- 

 rates it from the femur, in 

 the lower part of its course. 



The femoral vein, at Pou- 

 part's ligament, lies close to 

 thfe inner side of the artery, 

 separated from it by a thin 

 fibrous partition, but, as it 

 descends, gets behind it, and 

 then to its outer side. 



The internal saphenous nerve 

 is situated on the outer side 

 of the artery, in the middle 

 third of the thigh, beneath 

 the aponeurotic covering, but 

 not usually within the sheath 

 of the vessels. Small cuta- 

 neous nerves cross the front 

 of the sheath.
