Which layers compose the meninges membrane?

The meninges are protective membranes that surround the brain and spinal cord, consisting of three distinct layers: the dura mater, arachnoid mater, and pia mater.

The dura mater is the outermost layer and is known for its toughness and durability, providing a strong protective covering. The arachnoid mater is the middle layer, characterized by its web-like appearance and acting as a cushion for the brain. The pia mater is the innermost layer, which is delicate and closely adheres to the surface of the brain and spinal cord, providing nutrients and protection.

This structure is crucial for maintaining the health and stability of the central nervous system by providing support, limiting the movement of the brain, and containing cerebrospinal fluid, which further protects the brain and spinal cord from injury. The other options do not accurately pertain to the meninges; they refer to different anatomical structures or types of membranes not relevant to the protective coverings of the central nervous system.
