cranial dura mater

[TA] the intracranial dura mater, consisting of two layers: the outer periosteal layer that normally always adheres to the periosteum of the bones of the cranial vault; and the inner meningeal layer that in most places is fused with the outer. The two layers separate to accommodate meningeal vessels and large venous (dural) sinuses. The meningeal layer is also involved in the formation of the various dural folds, such as the falx cerebri and tentorium cerebelli and is comparable to and continuous with the dural mater of the spinal cord. The cranial epidural space is then an artifactual space between the bone and the combined periosteum/periosteal layer of the dura mater realized only as a result of pathologic or traumatic processes and is neither continuous with or comparable to the vertebral epidural space. Synonym(s): dura mater cranialis [TA], dura mater encephali ☆ , cerebral part of dura mater, dura mater of brain
