The CNS is protected by the skeletal system (skull and vertebral column), and underneath by membranes of connective tissue, called meninges. In addition, the CNS has a privileged blood supply, as suggested by the blood-brain barrier. Because of this privilege, the CNS needs specialized structures for the maintenance of circulation.
