APPLIED RADIOLOGICAL ANATOMY

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: -They’re known as: Dura mater: This is the outer layer, closest to your skull. Arachnoid mater: This is the middle layer. Pia mater: This is the inner layer, closest to your brain tissue.

Detailed explanation-3: -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.

Detailed explanation-4: -There are two subdivisions of arachnoid mater surrounding the subarachnoid space, the dorsal layer and the ventral layer. The dorsal layer covers internal cerebral veins and fixes them to the surrounding tela choroidea.

Detailed explanation-5: -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.
