In human anatomy, the cephalic vein (also called the antecubital vein) [1] is a superficial vein in the arm. It is the longest vein of the upper limb. It starts at the anatomical snuffbox from the radial end of the dorsal venous network of hand, and ascends along the radial (lateral) side of the arm before emptying into the axillary vein.

It contains the cephalic vein, [4] and deltopectoral fascia, which is a layer of deep fascia that invests the three structures that make up the border of the triangle. The deltoid branch of the thoracoacromial artery also passes through this triangle, giving branches to both the deltoid and pectoralis major muscles.
One or two deltopectoral lymph nodes (or infraclavicular nodes) are found beside the cephalic vein, between the pectoralis major and deltoideus, immediately below the clavicle. They are situated in the course of the external collecting trunks of the arm.
The veins of the arm carry blood from the extremities of the limb, as well as drain the arm itself. The two main veins are the basilic and the cephalic veins . There is a connecting vein between the two, the median cubital vein , which passes through the cubital fossa and is clinically important for venepuncture (withdrawing blood).
The median cubital vein is a superficial vein of the arm. [1] It lies on the anterior aspect of the elbow, [2] in the cubital fossa superficial to the bicipital aponeurosis. It bridges the cephalic vein and the basilic vein. [3] The median cubital vein receives a number of tributaries from the anterior forearm.
It is the location through which the cephalic vein passes and where the coracoid process is most easily palpable. See also. Deltopectoral triangle; Additional images
However, it receives the efferents of all the other axillary glands. The efferent vessels of the subclavicular group unite to form the subclavian trunk , which opens either directly into the junction of the internal jugular and subclavian veins or into the jugular lymphatic trunk ; on the left side it may end in the thoracic duct .
