abdomiualis of the M. pectoralis ; here the vein curves round to pass 

 forwards between the fibres of this muscle to its inner border where 

 it terminates by joining- the brachial vein. In the whole of this 

 lengthy ■ course the vein receives numerous branches from the 

 neighbouring- parts.

 dorsales : the vein courses 

 superficially along the 

 outer side of the forearm 

 to the elbow. 



/3. The ulnar vein 

 [Vena nlnaris) arises from 

 the veins in the palm of the 

 hand^ and courses towards 

 the elbow, lying deeply 

 between the muscles of 

 the inner and outer sur- 

 faces of the forearm. In 

 the elbow the vein be- 

 comes superficial near the 

 tendon of the M. sterno- 

 cleidoradialis, and joins 

 the radial vein to form 

 the brachial vein. 



The cutaneous veins 

 of the fore-limb follow 

 courses corresponding 



with those of the arteries,
