GENERAL HISTOLOGY

Detailed explanation-1: -The most superficial layer of the meninges is the dura mater. While it has two layers in the cranial segment, the spinal dura mater only has the deep meningeal layer.

Detailed explanation-2: -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-3: -The dura mater often gets referred to as merely the dura. It is one of the layers of connective tissue that make up the meninges of the brain (pia, arachnoid, and dura, from inside to outside). It is the outermost layer of the three meninges that surround and protect the brain and spinal cord.

Detailed explanation-4: -There are three layers from superficial to deep the: dura mater; arachnoid mater; pia mater. Each layer of the meninges serves a vital role in maintenance and function of the central nervous system.
