Veins of the hand
Most blood from the hand drains to the dorsal venous arch on the back of the hand, which gives rise to the cephalic and basilic veins. The deep veins of the palm are paired venae comitantes that run with the palmar arterial arches and their branches.
Key points
- Dorsal venous arch: proximal to the MCP joints.
- Lateral end → cephalic vein; medial end → basilic vein.
- Deep palmar veins = venae comitantes of the palmar arches.
- Deep and superficial veins communicate through the interosseous spaces.
- Vessels: mesodermal, from angioblastic tissue.
- Vein: thin wall, adventitia thickest, valves.
- Veins hold ~70% of the blood.
