Chapter 8 deals with the blood supply of the central nervous system (CNS). Regulatory mechanisms ensure that the brain is prioritized before all other organs. There is a high degree of autoregulation. The blood-brain barrier ensures that the CNS exerts strict control of what is let in. The internal carotid artery supplies most of the cerebral hemispheres, whereas the vertebral artery supplies the brain stem and the cerebellum. Communicating arteries at the base of the skull establish anastomoses between the posterior (vertebral) and the anterior (internal carotid) cerebral circulations. The venous blood drains into venous sinuses.
