The correct order of the meninges from superficial to deep is:
- Dura mater
- Arachnoid mater
- Pia mater
To explain further, the dura mater is the outermost layer and is tough and protective. It provides the first line of defense against physical impacts. Beneath the dura mater lies the arachnoid mater, which is a web-like structure that helps cushion the brain and spinal cord. Finally, the pia mater is the innermost layer, closely adhering to the surface of the brain and spinal cord, providing a delicate barrier that supports blood vessels supplying the nervous tissue.
