Document Summary
Venous return in the upper limb is facilitated by blood pressure, subatmospheric intrathoracic pressure, arterial pressure, arterial pulsation, skeletal muscle contraction and valves that limit back flow. Superficial veins form the dorsal arch of the hand. These veins give rises the 1asilica vein and the cephalic vein medial and lateral respectively. This is on the medial side of the forearm = the ulna side. This vein then continues and is renamed the axillary vein. This is on the lateral side of the superficial forearm = the radial side. It runs in between the tendons of the extensor pollicis longus and the extensor pollicis brevis. This vein runs in the groove between pectoralis and deltoids. It connects to the axillary artery at the proximal axilla. This lies in the roof of the cubital fossa and connects both the basilica and cephalic vein. This is the continuation of the basilica vein. Commences at the lower boarder of the tendon of latissimus dorsi.
