Which meninges layer lies between the dura and the pia mater?

Explanation:
The arachnoid mater sits between the dura mater and the pia mater. The dura is the tough outer layer, and the pia is the thin membrane closely adherent to the brain surface. The arachnoid is a middle, delicate layer that forms the boundary for the subarachnoid space (which contains cerebrospinal fluid), while the space between dura and arachnoid is the subdural space (a potential space, not a true space under normal conditions).
