The median cephalic vein passes upwards and outwards, and 

 opposite the external condyle of the humerus joins the radial 

 vein to form the cephalic vein. The median basilic vein similarly 

 forms the basilic vein opposite the internal condyle by joining 

 with the anterior and posterior ulnar veins. 



The upper arm contains only two large veins. 



1. The Basilic vein commences opposite the inner side of the 

 bend of the elbow, and passing upwards on the inner side of 

 biceps to the middle of the arm it pierces the deep fascia, and 

 opposite the lower border of teres major becomes the axillary 

 vein. 



2. The Cephalic vein commences at the outer side of the bend 

 of the elbow and ascends* on the outer side of biceps. It then 

 pierces the deep fascia, and passing between the adjacent 

 borders of the deltoid and pectoralis major muscles, it pierces 

 the costo-coracoid membrane and enters the third part of the 

 axillary vein.
