Brachial vein is considered a deep vein as it lies deep to the muscle. It runs the same course as the brachial artery. It runs almost vertically starting at the cubital fossa (at the bend of the elbow) to the lower border of the teres major muscle.

ORIGIN AND CONTINUATION

Brachial vein is formed at the level of the bend of the elbow (same level where brachial artery bifurcates) when ulnar and radial veins join together.

It ends at the teres major muscle where the brachial vein joins the basilic vein which then continues as the axillary vein.

DRAINAGE AREA

Brachial vein drains the area of the arm. It takes the deoxygenated blood from the radial and ulnar veins as well.

Brachial vein also drains some of the muscles of the upper arm like the biceps brachii muscle and the triceps brachii muscle.
