several other branches from the axillary region, and ter- 

 minates in the subclavian. 



The subclavian vein crosses the first rib and passes 

 below the clavicle; it unites with the internal jugular 



vein to form the innominate 



vein. 



VEINS OF THE LOWER EX- 

 TREMITIES 



The deep wins of the leg 

 accompany the arteries in 

 pairs, and form the venae 

 comites of the anterior and 

 posterior tibial arteries. The 

 tibial veins unite and form 

 the popliteal vein. 



The popliteal vein passes 

 through the popliteal space 

 and to the outer side through 

 an opening in the adductor 

 magnus muscle, and becomes 

 the femoral vein. It usually 

 contains four valves, and it 

 also receives blood from the 

 short saphenous vein. 



The femoral vein com- 

 mences at-*the owning in the 

 adductor magnus muscle, and 

 is enclosed in the femoral 

 sheath; it enters the pelvis 



beneath Poupart's ligament, and then becomes the ex- 

 ternal iliac vein. The valves are about five in number. 

 It receives several veins from the muscular structure, as 

 well as the deep femoral and the long saphenous veins. 

 The deep femoral is made up of small branches that
