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.
There are three layers of meninges around the brain and spinal cord (these are continuous between the two structures). The outermost layer is the Dura mater, the toughest and â¦ most protective layer. The middle is the arachnoid layer, and the pia mater is the innermost layer.The protective layers of the brain are the 3 meninges. From the outermost layer to the innermost layer, they are the dura mater, the arachnoid, and the pia mater.he meninges are composed of the 1) Dura mater is the layer of meninges closest to â¦ the skull resting on top of the arachnoid membrane attached to the skull in several pints, the dura mater is made up of a fibrous material that protect the brain like tight-fitting cap.
