This interactive FlashTM animation depicts aortic arch proliferation and differentiation. It begins with a dorsal view of the two chambered heart along with major embryonic vessels. Clicking allows users to see aortic arches elongate from the aortic sac to fuse with the aortae. Clicking again shows the sections of the aortic arches and aortae elongating, fusing or regressing to form the pulmonary artery, aortic trunk, brachiocephalic artery and carotid arteries. At this point users can highlight vessels by passing the cursor over them. When a user clicks a highlighted vessel the animation quickly reverses back to the aortic arch stage. The highlighting is maintained, so users can see which sections of the arches and aortae contribute to the vessel. Clicking again causes the animation to progress more slowly so users can observe how the different sections elongate, fuse or regress to form the vessel.
