cerebral artery

Cerebral arteries are the arteries that supply blood to the cerebral cortex of the brain. Blood reaches the brain through two main pathways: the internal carotid arteries and the vertebral arteries. The internal carotid arteries branch into the anterior and middle cerebral arteries, while the vertebral arteries form the posterior cerebral arteries.12

These arteries create a network at the base of the brain known as the circle of Willis, which ensures a continuous blood supply to the brain. A blockage in a cerebral artery can lead to an ischemic stroke, a condition where blood flow to the brain is reduced. The brain has a high demand for blood, and despite the extensive arterial network, blood supply can be precarious.321
