What are the 5 regions of space and meninges between the outer layer of meninges and the cerbral cortex?

The five regions of space between the outer layer of the meninges and the cerebral cortex are the epidural space, subdural space, arachnoid mater, subarachnoid space, and pia mater. The epidural space is located between the dura mater and the skull, while the subdural space lies between the dura mater and arachnoid mater. The arachnoid mater is a web-like structure, followed by the subarachnoid space filled with cerebrospinal fluid, and finally, the pia mater directly covers the cerebral cortex. These layers protect the brain and provide cushioning, nutrients, and waste removal.
