[TA]
origin, right from brachiocephalic, left from arch of aorta; runs superiorly in the neck and divides opposite upper border of thyroid cartilage (C-4 vertebral level) into terminal branches, external and internal carotid.

common carotid artery

Etymology: L, communis + Gk, karos, heavy sleep, arteria, airpipe
one of the major arteries supplying blood to the head and neck. Each divides into an external carotid and an internal carotid. Branches of the external carotid supply the face, scalp, and most of the neck and throat tissues. The internal carotids supply the brain and other tissues generally accessible from within the skull, as the eyes.

common carotid artery

A major artery to the head. The left common carotid usually arises from the aortic arch proximal to the left subclavian; the right common carotid is a branch of the brachiocephalic artery. Each common carotid artery runs rostrally in the carotid sheath and enters the neck (behind the sternocleidomastoid muscle) without branching; in the neck, between the level of the top of the trachea and the floor of the mouth, each common carotid artery divides into an internal and an external carotid artery.
