 anastomosing with the digital arteries. 



VEINS OF THE INFERIOR EXTREMITY. 



FIG. 261. The veins of the lower extremity, like 



those of the upper, are divided into the 

 superficial and deep. The superficial veins 

 are situated immediately beneath the skin, 

 and consist of the internal and external 

 sapliena. 



The internal sapliena begins on the inner 

 and upper part of the foot, ascends in front 

 of the internal malleolus, along the inner 

 portion of the leg to the inner condyle, 

 behind which it passes ; from this it still 

 ascends along the inner and anterior part 

 of the thigh to within two inches of Pou- 

 part's ligament, where it penetrates the 

 fascia lata to join the femoral vein. In 

 this course it receives numerous cutaneous 

 veins, and at its termination is joined by 

 the pudic, superficial epigastric, and su- 

 perficial circumflex veins. 



The external sapliena begins at the outer 

 ankle and dor sum of the foot, ascends on 

 the back of the leg to the ham, where it 

 joins the popliteal vein. 



The deep veins accompanying the arte- 

 ries have the same names, and are two 

 for each artery, called venae comites; 

 hence we have anterior, posterior tibial and peroneal veins, 

 uniting to form the popliteal, which is superficial to the 

 artery. After traversing the popliteal space to the opening 

 in the tendon of the adductor magnus, it changes its name 

 to femoral. From this point the femoral, which is here on 



FIG. 261 represents the Saphena Major Vein, a Superficial epigastric vein, 

 ft Internal pudic vein, c Superficial circumflex vein, d Orfgin of saphena 

 major, e Its termination in the femoral vein.
