The Meninges (or coverings)of Brain and Spinal Cord The brain and spinal cord are enclosed by three layers of membranes,the meninges: The dura mater,an outer tough and dense protective membrane. The arachnoid,and intermediate spiderweb-like delicate one. The pia mater,an innermost thin translucent,more delicate and fibrous membrane,which is rich in blood vessels and is adherent to the surface of the brain and spinal cord. The three membranes of the brain and spinal cord are continuous at the foramen magnum
