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: -INVESTING MEMBRANES (MENINGES) Three membranes surround the spinal cord: The outermost is the dura mater (dura), the next is the arachnoid, and the innermost is the pia mater (pia) (Figs 6–1 and 6–2). The dura is also called the pachymeninx, and the arachnoid and pia are called the leptomeninges.
Detailed explanation-3: -10-2 What are the names of the three layers of the meninges from the outermost to the innermost? The three layers of the meninges are the dura mater, arachnoid, and pia mater.
Detailed explanation-4: -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. These together contribute to the dura being a thick, dense, fibrous membrane that is quite inelastic.
