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.
