). The CCA is the main channel for sup-
plying this oxygenated blood. It commonly exists as a bifurcation from which the
ECA and ICA are originated.
The left and right CCA branches out from the aortic arch in the thoracic region
and the brachiocephalic artery respectively (Fig.

Components of the carotid arterial network. The carotid bifurcation comprises the Com-
mon Carotid Artery (
CCA
), the Internal Carotid Artery (
ICA
) and the External Carotid Artery
(
ECA
) at the neck and the head. The carotid artery serves the function of supplying oxygenated
blood to the cerebral region
