Introduction

Bovine Arch

Bovine Arch

The bovine arch, refers a common branching patten variant of the aortic arch, where the brachiocephalic artery (aka innominate) shares a common origin with the left common carotid artery.

In actuality it is a misnomer as the true bovine arch – i.e that found in cattle – comprises a common single brachiocephalic trunk which trifurcates into bilateral subclavian arteries and a single bicarotid trunk. This variation is very rare in humans.
