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
It ends at the teres major muscle where the brachial vein joins the basilic vein which then continues as the axillary vein.
Brachial vein drains the area of the arm. It takes the deoxygenated blood from the radial and ulnar veins as well.
