In my talk, I will first briefly review the Anatomy and then, the Physiology of the Cerebral Circulation and finish off with the basic Pathophysiology, as it relates to cerebrovascular diseases. Arterial blood is supplied to the brain via the two internal carotid arteries,

and the two vertebral arteries, the latter merging to form the basilar artery. At the base of the brain, the internal carotid divides to form the anterior and the middle cerebral arteries, abbreviated as ACA and MCA respectively, and the basilar artery divides to form the two posterior cerebral arteries PCA. However, one also finds an anterior communicating artery, ACom, between the two ACAs and a posterior communicating artery, PCom, between the ICA and PCA on each side. As a result, the Circle of Willis is formed, which allows the anterior and posterior systems, as well as the right and left sides of the brain to communicate in terms of arterial blood supply.
