the vein feeding the superior vena cava, collecting blood from the subclavian and jugular veins. See also innominate vein.
The brachiocephalic vein is formed by the merger of the subclavian and internal jugular veins in the root of the neck. The right brachiocephalic vein is about 2.5 cm long and the left is about 6 cm long. The right and the left brachiocephalic veins join, behind the junction of the right border of the sternum and the right first costal cartilage, to form the superior vena cava. Tributaries of both brachiocephalic veins include the vertebral, internal mammary, and inferior thyroid veins; the left brachiocephalic vein also receives the left superior intercostal, thymic, and pericardial veins.See: illustration for illus.
