The pharyngeal arches, also known as visceral arches, are structures seen in the embryonic development of vertebrates that are recognisable precursors for many structures. In fish, the arches are known as the branchial arches, or gill arches.
In the human embryo, the arches are first seen during the fourth week of development. They appear as a series of outpouchings of mesoderm on both sides of the developing pharynx. The vasculature of the pharyngeal arches is known as the aortic arches.
In fish, the branchial arches support the gills.
The aortic arch is the section of the aorta between the ascending and descending aorta. As it arises from the ascending aorta, the arch runs slightly backward and to the left of the trachea. The distal segment of the aortic arch then traverses downwards at the fourth thoracic vertebra.
