The tough, fibrous outer meningeal layer is called the

Explanation:
The tough outer fibrous layer of the meninges is the dura mater. It forms the protective outer covering around the brain and spinal cord, giving structural support and protection. Beneath it lies the arachnoid mater, a delicate, web-like middle layer, and the innermost layer, the pia mater, closely follows the contours of the brain and spinal cord. Dural sinuses are venous channels within the dura that drain blood from the brain, not a separate protective layer. So the outer protective layer you’re asking about is the dura mater.
