GENERAL HISTOLOGY

Detailed explanation-1: -The dura mater is composed of two layers: the periosteal/endosteal layer and the meningeal layer. The dural venous sinuses are between these two layers. The dura folds to form septa that create the falx cerebri, tentorium cerebelli, falx cerebelli, and diaphragma sellae.

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: -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 spinal dura mater is a fibrous, non-adherent, tough layer surrounding the spinal cord. It is separated from the wall of the vertebral canal by the epidural space. This space contains loose areolar tissue and a network of internal vertebral venous plexuses.
