The superficial femoral artery is only superficial where it lies in Scarpa's tri- 

 angle. Here it is covered by the skin, superficial and deep fascia, and crossed 

 by the internal cutaneous branch of the anterior crural nerve. In Hunter's canal 

 it is more deeply seated, being covered by the integument, the superficial and 

 deep fascia, the Sartorius and aponeurotic covering of Hunter's canal. The 

 internal saphenous nerve crosses the artery from '.vithout inward. Behind, the 

 artery lies at its upper part on the femoral vein and the profunda artery and 

 vein, which separate it from the Pectineus muscle, and lower down on the Adduc- 

 tor longus and Adductor magnus muscles. To the outer side is the long saphe- 

 nous nerve and the nerve to the Vastus internus, the Vastus internus muscle, 

 and, at its lower part, the femoral vein. To the inner side is the Adductor 

 longus above and the Adductor magnus and Sartorius below.

Ike femoral vein, atPoupart's ligament, lies close to the inner side of the 

 artery, separated from it by a thin fibrous partition; but lower down it is behind 

 it, and then to its outer side. 



The internal saphenous nerve is situated on the outer side of the artery, in the
