(5) The median vein begins in the plexus on the wrist and 

 ascends along the front of the forearm to the bend of the elbow, 

 where it bifurcates into the median basilic and median cephalic 

 veins. 



(6) The median basilic is directed upward and joins the common 

 ulnar to form the basilic vein. The median basilic is the vein
