Latin, 'royal'. From the mistaken belief that the left basilic was connected to the spleen and right to the liver, hence bloodletting these veins would drain impurities from the two organs.

The basilic vein is a major vein of the forearm and upper arm. It is a tributary of the axillary vein.



The basilic vein is a continuation of the medial side of the dorsal venous network of the hand. It runs in the superficial fascia of the posteromedial forearm, inclining anteriorly in the proximal half of the forearm to lie on the anteromedial side of the cubital fossa, where it is joined by the median cubital vein.

It runs proximally in the upper arm between biceps brachii and pronator teres, crossing the brachial artery. Fibres of the medial cutaneous nerve of the forearm split around the vein here. It continues along the medial border of biceps, perforating the deep fascia just distal to the midpoint of the upper arm. Here it runs alongside the medial side of the brachial artery to the lower border of teres major, where it continues as the axillary vein.
