Which statement correctly describes the epidural space?

Explanation:
The epidural space is the area outside the dura mater, located between the dura and the surrounding bone (the skull in the head, or the vertebral wall in the spine). It surrounds the dura, not within the brain tissue and not between the dura and the arachnoid. That’s why describing it as the space on or around the dura mater is correct. Clinically, this space can fill with blood in an epidural hematoma after head trauma, typically from rupture of a meningeal artery. The other descriptions refer to regions outside the epidural space or inside brain tissue, which is why they don’t fit.
