what does brachiocephalic mean
The brachiocephalic artery (or brachiocephalic trunk or innominate artery) is an artery of the mediastinum that supplies blood to the right arm and the head and neck.he innominate artery usually gives off no branches, but occasionally a small branch, the thyreoidea ima, arises from it. Other times, it gives off a thymic or bronchial branch. It varies greatly in size, and appears to compensate for deficiency or absence of one of the other thyroid vessels.
