The aortic arches or pharyngeal arch arteries (previously referred to as branchial arches in human embryos) are a series of six paired embryological vascular structures which give rise to the great arteries of the neck and head. They are ventral to the dorsal aorta and arise from the aortic sac.
The aortic arches are formed sequentially within the pharyngeal arches and initially appear symmetrical on both sides of the embryo,[1] but then undergo a significant remodelling to form the final asymmetrical structure of the great arteries.[1][2]
