The anterior circulation derives blood from the bilateral internal carotid arteries ICA and supplies blood to the majority of the cerebral hemispheres including the frontal lobes parietal lobes lateral temporal lobes and anterior part of deep cerebral hemispheres. Corpora callosa is the largest of the commissural fibers linking the cerebral cortex of the left and right cerebral hemispheres. The circle of Willis also called Willis circle loop of Willis cerebral arterial circle and Willis polygon is a circulatory anastomosis that supplies blood to the brain and surrounding structures in reptiles birds and mammals including humans.

The lack of blood flow kills brain cells and impairs function in that region. It is named after Thomas Willis 16211675 an English physician. A brain AVM may also be a part of more extensive disease eg cerebrofacial arteriovenous.
