Ventrolateral view, left side

There is only one brachiocephalic artery.  It is the third branch off the aorta.  It gets its name because it serves the arm and head.  It gives rise to the right subclavian artery and the right and left common carotid arteries in most cats.  In some cats it gives rise to the bicarotid trunk instead of the left and right common carotid arteries.
