It is the outermost of the three meningeal coverings. It consists of two layers: the periosteal dura linking the inner surface of the skull and the meningeal dura that lies above the arachnoid dural membrane. The meningeal layer draws away from the periosteal layer and certain locations to form the dural reflections.

The other two meningeal layers are the pia mater and the arachnoid mater. The dura surrounds the brain and the spinal cord and is responsible for keeping in the cerebrospinal fluid[Wikipedia:Dura_mater]. dura ectomeninx
