The left common carotid artery, coming from the arch of the aorta, rises and ends in the same place, the thyroid cartilage, which is divided into the external and internal carotid. It is closely related anatomically to the carotid body, a small group of chemoreceptors and supporting matrix that reacts to the change in the composition of the blood flowing through the bifurcation. The origin of the ICA in the neck at approximately C4–C5 makes it readily accessible to examination by auscultation (for bruit) and noninvasive vascular studies.
