 | | The external layer of the dura mater, derived from the internal layer of cranial periosteum, is adherent to the inner surface of the skull, and continuous with the ectocranial periosteum through the foramina of the skull. |
 | | Pia mater is a delicate layer constituting with the arachnoid the leptomeninges (slender membranes). |
 | | The pia mater, however, adheres closely to the irregular contours of the brain and spinal cord, and the width of the subarachnoid space becomes deeper in the region of major sulci, containing more amounts of cerebrospinal fluid, forming the subarachnoid cisterns. |
