Detailed explanation-1: -Three layers of membranes known as meninges protect the brain and spinal cord. The delicate inner layer is the pia mater. The middle layer is the arachnoid, a web-like structure filled with fluid that cushions the brain. The tough outer layer is called the dura mater.

Detailed explanation-2: -The deepest layer of the meninges, the pia mater, is composed of two layers and, unlike the arachnoid, follows the contours of the sulci and gyri.

Detailed explanation-3: -Your arachnoid mater, the middle layer of your meninges, lies directly below your dura mater. It’s a thin layer that lays between your dura mater and pia mater. It doesn’t contain blood vessels or nerves.

Detailed explanation-4: -The layers are the dura, arachnoid, and pia mater. The dura is a thick fibrous layer inside the surrounding bones, and the pia clings to the surface of the brain and spinal cord.
