Subdural space is best described as which location?

Explanation:
The subdural space is the area between the dura mater and the arachnoid membrane. It’s a potential space—normally there isn’t a real gap there, but it can open up if blood or other fluid accumulates, such as with a subdural hematoma. This is distinct from the epidural space (between the skull and the dura), the subarachnoid space (between the arachnoid and pia mater where CSF flows), and from the brain’s internal tissue (parenchyma) or the ventricles (CSF-filled cavities inside the brain).
