324 FEMORAL ARTERY. 



and by the superficial and deep fasciae. The lower two-thirds are coverea 

 by the sartorius muscle. To its outer side the artery is first in relation 

 with the psoas and iliacus, and then with the vastus internus. Behind it 

 rests upon the inner border of the psoas muscle ; it is next separated from 

 the pectineus by the femoral vein, profunda vein and artery, and then lies 

 on the adductor longus to its termination : near the lower border of the 

 adductor longus, it is placed in an aponeurotic canal, formed by an arch 

 of tendinous fibres, thrown from the border of the adductor longus and 

 the border of the opening in the adductor magnus, to the side of the 

 vastus internus. To its inner side it is in relation at its upper part with 

 the femoral vein, and lower down with the pectineus, adductor longus, 

 and sartorius. 



The immediate relations of the artery are the femoral vein, and two 

 saphenous nerves. The vein at Poupart's ligament lies to the inner side 

 of the artery ; but lower dow T n gets altogether behind it, and inclines to its 

 outer side. . The short saphenous nerve lies to the outer side, and some- 

 what upon the sheath for the lower two-thirds of its extent ; and the long 

 saphenous nerve is situated within the sheath, and in front of the artery 

 for the same extent.
