Question

Quizplus · Accepted Answer

The dura mater is the outermost layer of the meninges, the three membranes that surround and protect the brain and spinal cord. It is a tough, fibrous layer that adheres closely to the inside of the skull, forming a protective sheath around the brain. The pia mater is the innermost layer of the meninges, while the subarachnoid membrane is the middle layer, located between the arachnoid mater and pia mater. The dorsa mater and midsagittal sinus are not relevant to the protective sheath covering the brain.
