The pia mater is the innermost layer and it attaches to the surface of the brain and spinal cord; this layer is thin and delicate, and contains blood vessels. The arachnoid mater, or arachnoid, is the middle layer. Its loose arrangement of collagen fibers gives this layer web-like appearance. Cerebrospinal fluid, discussed next, is stored in the subarachnoid space, or space between the pia mater and the arachnoid mater. The dura mater is the outermost layer and lies against the skull and vertebral column.
