Maxillary artery

A branch of the external carotid artery that supplies blood to the face, jaws, muscles of mastication, and teeth. It originates from the first aortic arch.

What does the 6th arch become on the left side?

The 6th aortic arch on the left side forms the ductus arteriosus, which connects the pulmonary artery to the aorta before birth.

What does the 3rd arch form?

The 3rd aortic arch develops into the common carotid artery, which supplies blood to the head and neck, and the proximal portion of the internal carotid artery, which supplies blood to the brain.

What does the 4th arch form on the right side?

The right 4th aortic arch forms the proximal portion of the right subclavian artery.

What does the 1st arch form?

The first aortic arch ultimately contributes to the maxillary artery, which supplies face and jaws, the stapedial artery supplying the stapes in the ear, and the hyoid artery supplying the hyoid bone.

Which arch forms the pulmonary arteries?

The sixth aortic arch contributes to the proximal portions of both pulmonary arteries, the vessels carrying oxygen-depleted blood to the lungs.

What is the ductus arteriosus?

A temporary blood vessel connecting the pulmonary artery to the aorta in the fetus, allowing blood to bypass the lungs. It typically closes shortly after birth.
