In human anatomy, the cephalic vein (or antecubital vein[dubious - discuss]) is a superficial vein of the upper limb.It communicates with the basilic vein via the median cubital vein at the elbow and is located in the superficial fascia along the anterolateral surface of the biceps brachii muscle.Superiorly the cephalic vein passes between the deltoid and pectoralis major muscles (deltopectoral groove) and through thedeltopectoral triangle, where it empties into the axillary vein.The cephalic vein is often visible through the skin, and its location in the deltopectoral groove is fairly consistent, making this site a good candidate for venous access. Permanent pacemaker leads are often placed in the cephalic vein in the deltopectoral groove. The vein may be used for intravenous access, and is sometimes referred to as the 'House-man's Friend' because a large bore cannula may be easily placed.[citation needed]
