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 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.
Detailed explanation-3: -The primary function commonly attributed to meninges and CSF is to protect the central nervous system (CNS). This is mainly because meninges provide a tight anchoring of the CNS to the surrounding bones able to prevent side-to-side movement and providing stability.
