Science Main Index. The meninges is a series of membranes that cover the central nervous system. The meninges consist of three layers: the dura mater, the arachnoid mater, and the pia mater. These layers cover the brain and spinal cord with the primary function of protecting and nourishing the central nervous system.eninges of the Brain. The meninges covers and protects the central nervous system including the brain and spinal cord. The meninges consist of three layers: the dura mater, the arachnoid mater, and the pia mater. The dura mater is the outermost of the three layers making up the meninges.
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.
