Block7/Fig. 13 Meninges of central nervous system.

block7_30.jpg - Fig. 13 Meninges of central nervous system. The brain andspinal cord are covered by three layers of meninges. Thesurface of the nervous tissue is covered by a delicate layercalled the pia mater. Overlying the pia mater is a thickerfibrous layer, the arachnoid mater. The space between thepia and arachnoid layers is called the subarachnoid space.External to the arachnoid mater is a dense fibroelastic layercalled the dura mater. Note the white matter in the spinalcord is composed of myelinated axons.
