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: -(meh-NIN-jeez) The three thin layers of tissue that cover and protect the brain and spinal cord.

Detailed explanation-3: -The cranial dura mater is the outermost meningeal layer, consisting of dense irregular connective tissue. It is composed of two layers; The superficial layer is the periosteal cranial dura. It overlies the inner table of the cranial vault bones, acting like the periosteal layer of the cranium.

Detailed explanation-4: -The meninges are the connective tissue coverings of the brain and spinal cord. The outermost layer is the dura mater, a dense and tough tissue that is reduplicated to form the periosteum of the inner skull. Beneath the dura is the arachnoid, a network of loose connective tissue that lacks blood vessels.

Detailed explanation-5: -Dura Mater The outermost mater of the meninges, the dura, is composed of two layers: the periosteal layer that lies closest to the calvarium and the meningeal layer that lies closest to the brain tissue.
