In addition to these deep veins, two large subcutaneous veins, the basilic vein and the cephalic vein, are located in the arm.
The basilic vein passes vertically in the distal half of the arm, penetrates deep fascia to assume a position medial to the brachial artery, and then becomes the axillary vein at the lower border of the teres major muscle. The brachial veins join the basilic, or axillary, vein.
