Aortic arches model - human embryo

Description
One of three comparative models depicting the aortic arches in three different groups - human embryo, fish and mammal. The aortic arches or pharyngeal arch arteries 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, but then undergo a significant remodelling to form the final asymmetrical structure of the great arteries. These models were produced as part of the Jewell Models for Biology line, which were made by American company Turtox Products.
