GENERAL HISTOLOGY

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 outermost cover lying below the skull and vertebral column is doubly thick and is called Dura mater.

Detailed explanation-3: -Cranial dura mater has two layers called lamellae, a superficial layer (also called the periosteal layer), which serves as the skull’s inner periosteum, called the endocranium and a deep layer called the meningeal layer. When it covers the spinal cord it is known as the dural sac or thecal sac.

Detailed explanation-4: -Your brain and spinal cord are protected and supported by three meningeal layers. These membrane layers are the dura mater, arachnoid mater and pia mater.

Detailed explanation-5: -The tough outer layer of tissue that covers and protects the brain and spinal cord and is closest to the skull.
