Development of the Arterial System

Development of the Arterial System Formation The arterial system develops from the aortic arches and branches of the dorsal aorta. Aortic arch derivatives Aortic arch 1 has no derivative because it disappears soon after development. Aortic arch 2 has no derivative because it persists only during the early development. Aortic arch 3 forms the common carotid arteries and the proximal part of the internal carotid arteries. Aortic arch 4 forms the aortic arch on the left and the brachiocephalic artery and the proximal subclavian artery on the right. Aortic arch 5 has no derivative. Aortic arch 6 forms the proximal pulmonary arteries and ductus arteriosus Dorsal aorta 1. Posterolateral branches Form the intercostal, lumbar, vertebral, cervical, internal thoracic, and epigastric arteries, and arteries to upper and lower limbs. 2. Lateral branches Form the renal, suprarenal, and gonadal arteries. 3. Ventral branches Vitelline arteries form the celiac (foregut), superior mesenteric (midgut), and inferior mesenteric (hindgut) arteries. Umbilical arteries form a part of the internal iliac and superior vesical arteries. ◄.....Go back to the Gross Anatomy homepage
