Uberon definition : One of a series of paired embryological vascular structures formed within a pharyngeal
arch; in the adult, some of these vessels give rise to the great vessels[MP];
Uberon related term : pharyngeal arch arteries; aortic arch artery; pharyngeal arch artery; branchial aortic arches;
Uberon Development note : 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 Homology note : When vertebrates first appeared, they must have possessed a ventral and dorsal aorta
with aortic arches between them.[well established][VHOG];
Uberon Taxon note : Number varies - Lampreys have 8, hagfishes 15; only up to 6 appear in embryonic development
in most gnathostome fishes and all tetrapods;
