Upper Extremity Veins
A big network of tubular veins can be found beneath the upper extremity skin. This is because the upper extremity holds a lot of deep and superficial veins. The deeper veins are located well below the skin surface, and they run alongside the arteries. The deep and superficial palms of the hands run into the radial and ulnar veins, which are found on the arm.
The brachial vein refers to the combination of the cubital fossa, the radial veins and the ulnar veins. The medial side of the arm is where the veins basilica and cephalic can be found, and they serve as the main veins of the medial arm region. The brachial vein and the basilica vein meet at the humerus’ point, passing through the ulna vein. This meeting forms the bigger axillary vein. On the radial side of the arm, draining by the cephalic vein happens, and the blood moves upward to join the axillary vein, situated in proximity to the shoulder. The axillary vein then meets with the subclavian vein after it has passed under the first rib. The subclavian vein connects with the internal jugular vein, forming the brachiocephalic vein.
The superficial veins of the cubital fossa joins the cubital vein, then goes on to meet the cephalic vein and from there, conjoins with the basilica vein. Blood withdrawals from the body is commonly done through the medial cubital vein. The brachiocephalic veins - which make up the superior vena cava - do not have the typical valves that the rest of the body veins have.
