Arteries of the Brain

Conceptual Diagram of the Circle of Willis
The cerebral circulation has a unique system that allows for compensatory flow when any one of the 4 vessels is narrowed or occluded.
This cerebral circulation is centered on the circle of Willis which has two basic systems that feed it;
the carotid system (in this case salmon pink) and the vertebro-basilar system (brighter pink).
They both feed into the circle of Willis (bright red) via communicating branches.
The middle cerebral artery is the vessel that feeds into the COW by providing the anterior communicating artery.
The posterior cerebral artery connects via the posterior communicating artery.
Conceptually as depicted in this diagram the circle of Willis is the centre of the cerebral circulation and from it, blood flows into the anterior (bright green), middle (darker green) and posterior cerebral (maroon) regions.
