The name stems from the similarity of this variant with that of a normal bovine arch. A true bovine arch (as found in cattle) has a common single brachiocephalic trunk which trifurcates into bilateral subclavian arteries and a single bicarotid trunk. This variation is very rare in humans.
Presumably somewhere in the animal kingdom is an animal whose aorta actually branches like the so-called bovine pattern. Proposed names are feline/canine/lapine arch.
