There are two main superficial veins of the upper limb: The basilic vein and the cephalic vein.
Both of them arise from the dorsal venous arch which lies on the dorsum of hand and it has a network aspect.
From the medial end of the dorsal venous arch arises the basilic vein. And from the lateral end of the dorsal venous arch arises the cephalic vein.
The basilic vein begins as the continuation of the medial end of the dorsal venous arch of
the hand. It runs upwards along the back of the medial border of the forearm, winds round this border near the elbow to reach the anterior aspect of the forearm, where it continues upwards in front of the elbow and then along the medial side of the biceps brachii up to the middle of the arm, where it pierces the deep fascia and unites with the brachial veins to become continuous with the axillary vein at the lower border of the teres major.
From the radial aspect of the dorsal venous arch , the cephalic vein arches around the radial aspect of the forearm to course through the anterolateral forearm. It then passes upwards over the anterior elbow region and ascends lateraly to the biceps muscle to reach the deltopectoral groove. The vein then perforates the clavipectoral fascia to drain into the axillary vein.
