Meninges are crucial for what purpose?

The meninges are a critical set of membranes that serve the vital function of covering and protecting the brain and spinal cord. These three layers—dura mater, arachnoid mater, and pia mater—provide a supportive structure that helps to safeguard the central nervous system from trauma and infection. They also play a role in containing the cerebrospinal fluid, which cushions the brain and spinal cord, ensuring a stable environment for proper neurological function.

This protective feature is essential to prevent physical injury from impact and to maintain the delicate balance of the physiological processes that occur within the central nervous system. The other options listed do not pertain to the functions of the meninges, highlighting the importance of understanding specific anatomical roles in the human body.
