The meninges is a layered unit of membranous connective tissue that covers the brain and spinal cord. These coverings encase central nervous system structures so that they are not in direct contact with the bones of the spinal column or skull. The meninges are composed of three membrane layers known as the dura mater, arachnoid mater, and pia mater.
