Meninges refer to the protective membranes that surround the brain. Dura mater is the outer most meninx which forms a tough and fibrous cover. Pia mater is the deepest meninx and represent the delicate layer of connective tissue. Present between pia mater and dura mater is the arachnoid mater. Together, dura mater, arachnoid mater and pia mater make a membranous encasement to cover the brain and protect it from any injury.
