Carotid artery

Arteria carotis communis

The right common carotid arises from the brachiocephalic trunk; the left arises directly from the aortic arch. Each ascends in the carotid sheath lateral to the trachea and bifurcates at approximately the level of C3-C4 (upper border of thyroid cartilage) into internal and external branches.

Type Vessel
Body System Cardiovascular
Body Region Neck
Latin Name Arteria carotis communis
FMA ID 3939

Function

The common carotid arteries are the major blood supply to the head and neck. Each bifurcates into the internal carotid (supplies the brain) and external carotid (supplies the face, scalp, and neck structures) arteries.

Clinical Significance

Carotid artery stenosis is a major cause of ischemic stroke. Carotid endarterectomy removes atherosclerotic plaque. The carotid sinus reflex (baroreceptor) regulates blood pressure. Carotid dissection can cause stroke, especially in young adults.
