of the dorsum of the foot. It has two ends, called inner and outer. This vein 

 should be studied on your own feet in this simple way : Tie a bandage very 

 tightly around your leg eight inches below the knee. The pressure will retard 

 the return circulation and make all the superficial veins stand out. 



Long Saphenous Vein. This is the largest and longest superficial vein in 

 the body. It is in the deep layer of the superficial fascia. It is attended by the 

 long saphenous nerve below the knee. It begins at the inner end of the dorsal 

 arch of the foot (arcns dorsalis pedis), passes in front of the internal malleolus, 

 behind the inner tuberosity of the tibia and the inner condyle of the femur, and

opens into the common femoral vein, passing through the saphenous opening in 

 the fascia lata. This vein is ligated or obliterated in the radical operation for 

 varicose veins of the lower extremity. (Fig. 210.) 



The Short Saphenous Vein. This begins at the outer end ot the dorsal 

 arch of the foot, passes behind the external malleolus of the fibula, soon gains 

 the posterior mid-line of the leg, passes between the two heads of the gastroc- 

 nemius, and opens into the popliteal vein. This vein is attended by the short 

 saphenous nerve. 



The Long Saphenous Nerve. This is the longest cutaneous nerve in the 

 body. It is a branch of the anterior crural or femoral nerve. It is in Scarpa's
