The veins of the upper limb may be divided into deep verns, which accompany arteries
within the fascial sleeve, and superficial veins, which lie mostly outside the fascial sleeve
(see Fig 10-4). Blood from the digits and palm drains into the dorsal venous network. Cephalic (lateral) and basilic (medial) veins rise from this network and ascend the forearm,
where the median vein of the forearm arises. The cephalic vein lies laterally and empties
into the axillary vein, which is a direct continuation of the basilic vein and continues centrally as the subclavian and brachiocephalic veins before emptying into the superior vena
cava. The basilic vein lies medially and joins the brachial vein. The median cubital vein,
which is commonly used for venipuncture, lies over the antecubital fossa and serves as an
anastomosis between the cephalic and basilic veins (Fig 10-5).
