The meninges of the brain and spinal cord are continuous, being linked through the magnum foramen. Dura Mater.
They are composed of three membranes, called the pia mater, the arachnoid mater and the dura mater. Each layer of the meninges is a continuous layer, covering the entire brain and spinal cord.The pia mater is the innermost membrane and is the most delicate of the three layers. It also is the most closely fitting, running smoothly over the spinal cord and brain, following the contours of their surfaces.Within the pia mater is a network of capillaries that supply blood to the brain and spinal cord.hey are composed of three membranes, called the pia mater, the arachnoid mater and the dura mater. Each layer of the meninges is a continuous layer, covering the entire brain and spinal cord.
