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 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-3: -Cranial Meninges The meninges of the brain are continuous with those of the spinal cord and possess the same three layers. The most superficial meninge is the dura mater.

Detailed explanation-4: -Meninges are three layers of membranes that cover and protect your brain and spinal cord (your central nervous system [CNS]). 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-5: -The pia mater is the innermost layer of meninges. This thin, delicate membrane is tightly bound to the surface of the brain and spinal cord and cannot be dissected away without damaging the surface.
