Cerebral blood flow is directly proportional to cerebral perfusion pressure and inversely proportional to cerebral vascular resistance. Cerebral perfusion pressure in turn is the difference between systemic arterial pressure and intracranial pressure.

The right common carotid artery arises from the brachiocephalic. The left common carotid usually arises as the second arch vessel. The common carotids normally have no branches. The first branch of the subclavian artery on each side are the vertebral arteries, which ascend posterior to the carotids.
