Anatomy study note · Upper limb

Axillary vein

The deep vein of the axilla, formed at the lower border of teres major by the basilic vein and the venae comitantes of the brachial artery. The other deep veins of the limb are paired venae comitantes running beside the arteries.

Key points

• Basilic + brachial venae comitantes at teres major.
• Medial to the axillary artery.
• Becomes the subclavian vein at the 1st rib.
• Deep veins elsewhere = paired venae comitantes.
• Vessels: mesodermal, from angioblastic tissue.
• Vein: thin wall, adventitia thickest, valves.
• Veins hold ~70% of the blood.
