ANATOMY

Detailed explanation-1: -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-2: -The tough outer layer is called the dura mater.

Detailed explanation-3: -The meningeal layer of the dura mater is a durable, dense fibrous membrane that passes through the foramen magnum and is continuous with the dura mater of the spinal cord. The meningeal layer of the dura mater creates several dural folds that divide the cranial cavity into freely communicating spaces.

Detailed explanation-4: -Subdural Hematoma – A collection of blood trapped under the dura mater, the outermost membrane surrounding the brain and spinal cord.
