Aortic Arch Derivatives, CAP

Question 1

Aortic arch derivatives

Answer 1

1st - part of the maxillary artery, branch of the external carotid
2nd - stapedial artery and hyoid artery
3rd - common carotid artery and proximal part of the internal carotid artery
4th - on left, aortic arch; on right, proximal part of the right subclavian
6th - proximal part of the pulmonary arteries and (on left only) ductus arteriosus

Remember:
General Maximus the first ordered his men to (2) stampede and hide the second in command. Three guards slit his carotid on the commons and then brought him inside. Then, under the arch, the general proclaimed his new right hand man. Unfortunately, he took sick of an lung ailment from the moldy ducts and died soon after.
