Head and neck anatomy left subclavian artery. The head and neck are emptied of blood by the subclavian vein and jugular vein. The brachiocephalic artery or trunk is the first and largest artery that branches to form the right common carotid artery and the right subclavian artery. This artery provides blood to the right upper chest, right arm, neck, and head, through a branch called right vertebral artery. The right and left vertebral artery feed into the basilar artery and upward to the Posterior cerebral artery, which provides most of the brain with oxygenated blood.

Dorsal veins of the penis Dorsal veins of the penis In human anatomy, the dorsal veins of the penis comprise the superficial dorsal vein of the penis and the deep dorsal vein of the penis. The "superficial dorsal vein of the penis" drains the prepuce and skin of the penis, and, running backward in the subcutaneous tissue, inclines to the right or left, and opens into the corresponding superficial external pudendal vein, a tributary of the great saphenous vein. In contrast to the deep dorsal vein, it lies "outside" Buck's fascia. It is possible for the vein to rupture, which presents in a manner similar
