<P> CSF occupies the subarachnoid space ( between the arachnoid mater and the pia mater ) and the ventricular system around and inside the brain and spinal cord . It fills the ventricles of the brain , cisterns , and sulci , as well as the central canal of the spinal cord . There is also a connection from the subarachnoid space to the bony labyrinth of the inner ear via the perilymphatic duct where the perilymph is continuous with the cerebrospinal fluid . </P>
