It is formed by the dura mater, the tough outer layer of the meninges around the central nervous system. It contains cerebrospinal fluid (CSF), which cushions and supports neural tissue. Clinicians commonly refer to it when reading spine MRI\/CT scans or when planning spine and anesthesia procedures."}
