1Name the membrane that covers the frontal lobe and the three layers comprising themThe meninges are the three layers that envelop the brain and spinal cord. The meninges are the Pia, arachnoid and dura mater
2Name the liquid between 2 of these membrane layers.Cerebrospinal fluid fills the subarachnoid space between the arachnoid mater and pia mater.
