[TFD][VHOG] TAO:0005004 The third, fourth, and sixth arches, along with the seventh intersegmental arteries and the left dorsal aorta, are the primary contributors to the normal aortic arch and its major thoracic branches UBERON:0004342 UBERON:0004363 UMLS:C0003489 VHOG:0000122 When vertebrates first appeared, they must have possessed a ventral and dorsal aorta with aortic arches between them.[well established][VHOG] XAO:0000341 ZFA:0005004 a. arcuum pharyngeorum add specific artery derivatives aortic arch aortic arch artery aortic arches arteriae arcuum pharyngeorum branchial aortic arches branchial aortic arches branchial arch artery embryonic aortic arch artery pharyngeal arch arteries pharyngeal arch artery pharyngeal arch artery uberon presumptive structure pharyngeal vasculature structure with developmental contribution from neural crest
