The brachial vein is a component of the deep venous system of the upper limb. After forming from the radial and ulnar veins1, the brachial vein travels from the cubital fossa superiorly to become the axillary vein.
- origin: union of the ulnar and radial veins in the cubital fossa1
- location: courses superiorly in the upper arm, often in close proximity to the brachial artery1
- drainage: deep and superficial palmar venous arches2
- termination: union of the brachial and basilic veins at the inferior border of teres major forms the axillary vein3
