## Definition

the tough outer layer of the brain and spinal cord. It acts like a protective shell to keep these parts safe.

For teachers: the outermost of the three meninges that surround the brain and spinal cord. It is a tough, fibrous membrane that provides structural support and protection.

## Examples

- The dura covers the brain to protect it from injury.
- During the surgery, the surgeon carefully separated the dura from the surrounding tissue to access the brain.
- The dura mater is not merely a passive barrier; it contains blood vessels and serves as a site for the formation of the dural sinuses, which drain blood from the brain.
