Dura mater or dura, is a thick membrane that is the outermost of the three layers of the meninges that surround the brain and spinal cord. It is derived from mesoderm.
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.
The arterial blood supply to the dura mater is rich, complex and is derived from both the internal and external carotid systems. Endovascular management of a variety of intracranial diseases necessitates a thorough understanding of the dural arterial network
