Immediately in front of the most anterior pairof ostia, and thus at the root of the aorta cephalica, a lateral artery is likewise givenoff on each side. A little further forward there are two more lateral arteries runningdownwards, and embracing the oesophagus, so forming an cesophageal ring. From thiscesophageal ring arise
