Basilic vein

The basilic vein (Latin: vena basilica) is a major superficial vein of the upper limb that arises from the dorsal venous network of the hand. It begins from the ulnar side of the dorsal venous network of the hand and drains into the brachial vein in the upper arm.

Initially, the basilic vein travels on the dorsal side of the forearm. At the proximal third of the forearm, it passes to the anterior side. In the upper arm, the basilic vein travels along the medial side. In the middle region of the upper arm, it penetrates the brachial fascia together with the medial cutaneous nerve of the forearm. Finally, it flows into the brachial vein.
