Answer:
True.
Step-by-step explanation:
The cerebral arterial circle, also known as the circle of Willis, is an arterial anastomosis located at the base of the brain. It is formed by the joining of several major arteries, including the two internal carotid arteries and the basilar artery. This arterial circle provides collateral circulation to the brain, allowing for multiple pathways for blood flow and serving as a protective mechanism in case of occlusion or blockage of one of the arteries supplying the brain.
