Detailed explanation-1: -The tough outer layer is called the dura mater.
Detailed explanation-2: -Structure of the meninges One of these regions is the interhemispheric fissure, in which the falx cerebri, a flat sheet of dura mater that is suspended from the top of the cranium, runs to separate the right and left cerebral hemispheres.
Detailed explanation-3: -The subarachnoid space is the cerebrospinal fluid-filled space that exists between the arachnoid and the pia. Within the lateral ventricles of the brain, the choroid plexus produces CSF, which passes into the subarachnoid space via the foramina of Luschka.
Detailed explanation-4: -Cerebrospinal fluid (CSF) leak occurs when there is a tear or hole in the membranes surrounding the brain or spinal cord, allowing the clear fluid that surrounds and cushions those organs to escape.
