Shoulder veins

Vv. brachiocephalicae dextra et sinistra, brachiocephalic veins, which form the superior vena cava, are in turn obtained by each fusion v. subclaviae and v. jugularis internae. The right brachiocephalic vein is shorter than the left, only 2–3 cm long having formed behind the right sternoclavicular joint, it goes obliquely downwards and medially to the confluence with the same vein of the left side. Front right brachial head vein covered by mm. sternocleidomastoideus, sternohyoideus and sternothyroideus, and below – cartilage I ribs. The left brachiocephalus is approximately twice as long as the right. Formed behind the left sternoclavicular joint, it goes behind the sternum handle, separated from it only by the fiber and thymus gland, right and down, to the confluence with the right brachiocephalic vein; closely adjoining at the same time with its lower wall to the bulge of the aortic arch, it crosses in front of the left subclavian artery and the initial parts of the left common carotid artery and brachiocephalic trunk. In the brachiocephalic veins fall vv. thyroideae inferiores and v. thyroidea ima, formed from the dense venous plexus at the lower edge of the thyroid gland, thymus vein, vv. vertebrates, cervicales et thoracicae internae.
