The Common Carotid Artery is a major blood vessel in the neck and head. It originates from the aorta in the chest and ascends in the neck to supply oxygenated blood to the head and neck.

Structure

The common carotid artery divides into the internal carotid artery and the external carotid artery. The internal carotid artery supplies blood to the brain, while the external carotid artery supplies blood to the face and neck.

Function

The common carotid artery is responsible for supplying oxygenated blood to the head and neck. It plays a crucial role in maintaining the brain's oxygen supply, which is essential for normal brain function.

Clinical significance

Blockage or narrowing of the common carotid artery can lead to stroke or transient ischemic attack (TIA). This is often caused by atherosclerosis, a condition where fatty deposits build up in the arteries.
