Extracranial Arteries

Aortic Arch

Refers to the second segment of the aorta. Also called the transverse aorta.

Innominate Artery (brachiocephalic artery)

Arises from the arch of the aorta and divides into the right subclavian artery and the right common carotid artery.

Subclavian Arteries

On the right side of the body, the subclavian arises from the innominate artery and supplies the right side of the neck and head and the right shoulder and arm.

On the left side of the body, the subclavian arises directly from the arch of aorta supplies the left side of the neck and head and the left shoulder and arm.

Common Carotid Artery

On the right side of the body, the right common carotid artery arises from the innominate artery.

On the left side of the body, the left common carotid artery arises directly from the arch of the aorta.

Internal Carotid Arteries

The right and left internal carotid arteries branch from their respective common carotid arteries and enter the skull to begin the cerebral circulation.

External Carotid Arteries

The right and left external carotid arteries branch from their respective common carotid arteries and supplies blood flow to the facial tissues.

Vertebral Arteries

The right and left vertebral arteries arteries arise from their respective subclavian arteries. In the skull the vertebral arteries join to become the basilar artery.
