Accessory cephalic vein

The accessory cephalic vein arises either from a small tributory plexus on the back of the forearm or from the ulnar side of the dorsal venous net-work; it joins the cephalic below the elbow.

In some cases the accessory cephalic springs from the cephalic above the wrist and joins it again higher up.

A large oblique branch frequently connects the basilic and cephalic veins on the back of the forearm.
