Document Summary
Same name as the spinal meninges as they are continous. Periosteal dura mater strongly adhered to inner skull. Meningeal dura mater bound to the periosteal. Arachnoid mater thin spindle spider web. Pia mater tender mother, follows cerebral cortex through gyri and sulci, carrying blood vessel. Dural venous sinuses in some areas of the skull the meningeal dura mater seperates from the periosteal dura mater which stays in contact with the bone. Dural reflections/dural folds when the meningeal and periosteal dura mater separate, portioning separate parts of the brain, brain stem and cerebellum. Cerebral veins drain from the white matter in the cerebral cortex into bridging veins which cross through the suba + subd space and empty into the dural venous sinuses (between 2 layers of dura) Venous channels embedded in the dural venous sinuses lead out of the skull to the ijv via the. Made by the dura mater: falx cerebri.
