Which of the following statements about the meninges is correct?

The meninges are a set of protective membranes that cover both the brain and spinal cord, serving a critical role in safeguarding these essential aspects of the central nervous system. The three layers of the meninges—dura mater, arachnoid mater, and pia mater—provide cushioning, protect against injury, and help contain cerebrospinal fluid. This fluid not only acts as a shock absorber but also facilitates nutrient exchange and waste removal for the brain and spinal cord.

Protection is vital for the proper functioning of the central nervous system, as any injury or trauma can lead to severe consequences, including neurological deficits or impairment. Thus, the statement that the meninges provide cushioning and protection is accurate and highlights the important physiological roles they play in maintaining the health and integrity of the central nervous system.
