FEMORAL ARTERY. 351 



superficial and deep fasciae. The lower two- thirds are covered 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 down gets altogether behind it, 

 and inclines to its outer side. The short saphenous nerve lies to the 

 outer side, and somewhat 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.

 don of the semi-tendinosus. 14. The femoral artery. 15. The superficial cir- 

 cumflexa ilii artery taking its course along the line of Poupart's ligament, to the 

 crest of the ilium. 2. The superficial epigastric artery. 16. The two external 

 pudic arteries, superficial and deep. 17. The profunda artery, giving off 18, its 

 external circumflex branch ; and lower down the three perforantes. A small 

 bend of the internal circumflex artery (8) is seen behind the inner margin of the 

 femoral, just below the deep external pudic artery. 19- The anastomotica 

 magna, descending to the knee, upon which it ramifies (6).
