DEEP SET. 



Posterior tibial : two venae comites, formed from external 

 and internal plantar, joining with the peroneal. Course same 

 as artery. 



Anterior tibial : two venae comites, continuation of vena 

 dorsales pedis, pierce interosseous membrane at upper part of 

 leg, and form the popliteal vein, by junction with the pos- 

 terior tibial veins, at the lower border of the popliteus muscle. 



Popliteal (see anterior tibial) : passes up to femoral aper- 

 ture in adductor magnus, there becoming the femoral ; re- 

 ceives sural, articular, and external saphenous veins. Four 

 valves. Placed superficial to artery, which it crosses as it 

 ascends, from within outwards. 



Femoral (see above) : passes from the opening in the 

 adductor magnus up to Poupart's ligament, there becoming 

 external iliac. Lies at first to outer side of artery, but higher up 

 crosses behind to its inner side. Receives muscular branches, 

 profunda femoris, and the internal saphenous. Four or five 

 valves. 



External iliac (see above) : from Poupart's ligament to 

 sacro-iliac synchondrosis, there uniting with the internal iliac 

 to form common iliac. On right side, lies to inside of artery 

 at first, but gradually passes behind it. On left side, alto- 

 gether on inside of artery. Receives deep epigastric and deep 

 circumflex iliac, and a. pubic vein from the obturator. 



Internal iliac : formed by the union of all of the venae 

 comites of the branches of the internal iliac artery, except 

 the ilio-lumbar veins which open into the common iliac. It 

 lies at first on the inner side, but finally gets behind the artery. 

 It has no valves. The visceral veins opening into the internal 

 iliac anastomose very freely and form a series of plexuses.
