The falx cerebelli is a small sickle-shaped fold of dura mater projecting forwards into the posterior cerebellar notch as well as projecting into the vallecula of the cerebellum between the two cerebellar hemispheres. [1] The name comes from two Latin words: falx, meaning "curved blade or scythe", and cerebellum, meaning "little brain". [2]
The falx cerebri is a strong, crescent-shaped sheet of dura mater lying in the sagittal plane between the two cerebral hemispheres. [3] It is one of four dural partitions of the brain along with the falx cerebelli, tentorium cerebelli, and diaphragma sellae; it is formed through invagination of the dura mater into the longitudinal fissure between the cerebral hemispheres.
The dura mater covering the spinal cord is known as the dural sac or thecal sac, and only has one layer (the meningeal layer) unlike cranial dura mater. The potential space between these two layers is known as the epidural space , [ 5 ] which can accumulate blood in the case of traumatic laceration to the meningeal arteries .
The straight sinus is situated within the dura mater, where the falx cerebri meets the midline of tentorium cerebelli. [1] It forms from the confluence of the inferior sagittal sinus and the great cerebral vein. [1] [2] It may also drain blood from the superior cerebellar veins and veins from the falx cerebri. [1]
The dura mater is a sac that envelops the arachnoid mater and surrounds and supports the large dural sinuses carrying blood from the brain toward the heart. The dura has four areas of infolding: Falx cerebri , the largest, sickle-shaped; separates the cerebral hemispheres .
"The mechanisms that rid waste from the brain are far more active when we sleep." When you have healthy sleep, the glymphatic system in your brain—which pumps out waste products—is more active ...

The subdural space (or subdural cavity) is a potential space that can be opened by the separation of the arachnoid mater from the dura mater as the result of trauma, pathologic process, or the absence of cerebrospinal fluid as seen in a cadaver.
