Termination. The axillary vein terminates by becoming continuous with the subclavian vein at the lateral border of the first rib 2.
Where does the axillary vein begin and end?
The axillary vein is a deep vein of the upper limb that is formed by the union of the brachial and basilic veins. It starts at the lower border of the teres major muscle and ascends medially through the axilla towards the 1st rib, where it is continued by the subclavian vein.
