Tributaries of cephalic vein Tributary of cephalic vein The Superficial Veins of the Superior Extremity. The superficial veins of the upper limb commence in the superficial fascia of the palm and dorsum of the hand and of the digits. The Veins of the Digits and Hand.—The proper volar digital veins are two or more fine longitudinal channels which lie in the superficial fascia of the volar aspects of the digits. They com- municate, proxim- ally, with a fine venous network which lies in the superficial fascia of the palm, and, at the proximal ends of the interdigital clefts, by means of intercapitular veins, which pass dorsally between the heads of the metacarpal bones, they open into the proper dorsal digital veins. The proper dorsal digital veins, two in each digit, anastomose freely together on the dorsal aspects of the digits. At proximal ends of the interdigital clefts they com- municate, through the intercapitular veins, with the proper volar digital veins, and then they unite to- gether to form an indefinite series of dorsal metacarpal.

The Veins of the Forearm and Arm.—The veins of the forearm emerge from the dorsal venous arch and from the volar venous, plexus, and they vary considerably in number and in size. As a rule there are two main longitudinal channels, the cephalic vein on the radial side and the basilic vein on the ulnar side. In some cases there is an additional median vein on the volar aspect of the forearm. The cephal
