- Pia mater. Pia mater (/ˈpaɪ.ə ˈmeɪtər/ or /ˈpiː.ə ˈmɑːtər/), often referred to as simply the pia, is the delicate innermost layer of the meninges, the membranes surrounding the brain and spinal cord. Pia mater is medieval Latin meaning tender mother. The other two meningeal membranes are the dura mater and the arachnoid mater.

Meninges and Cerebrospinal Fluid (Gross Anatomy of the Brain) Part 1 FIGURE 3-1 The coverings of the brain and spinal cord. (A) The brain and spinal cord are covered with three membranes: dura, arachnoid, and pia mater. The periosteal and meningeal layers of the dura are separate at the dural sinuses (e.g., superior sagittal sinus). At other places, the dura consists of fused periosteal and meningeal layers.

There are several differences in the meninges covering the brain and spinal cord, and, accordingly, they are discussed separately. The menin-ges consist of fibroblasts and collagen fibrils. The amount of collagen varies in different meningeal layers.

- This is like the pia mater, the very thin, delicate, vascular and innermost layer of the meninges. 'Pia' means 'delicate'. Its role is to provide oxygen and nutrients to the brain and spinal cord. To help remember the order of the meninges, think of the acronym PAD. A pad soaks things up from the bottom up.

Anatomy of the Brain: The Meninges The meninges are the coverings of the brain. They protect the brain by housing a fluid-filled space, and they function as a framework for blood vessels. The meninges have three layers: the dura mater, the arachnoid mater, and the pia mater. The arachnoid mater is attached to the pia mater by arachnoid trabeculae, which is a weblike matrix of connective tissue. The space between the two layers, the subarachnoid space, is filled with cerebrospinal fluid (CSF).

Name the layers of the meninges,and explain their functions.? Best Answer: The three layers are the dura mater, arachnoid membrane, and the pia mater. All three simply function to cover and protect the brain. The dura mater (Latin for hard mother) is the outer layer. Like its name implies, it surrounds the brain and spinal cord, providing a layer of durable, tough, and inelastic protection. The arachnoid membrane lies just below the dura mater. It resembles a matrix of spider webs, and hence the name. The pia mater (Latin for gentle mother) is the layer closest to the brain and spinal cord. It is actually intimately close to the brain and spinal cord.

The Meninges The dura mater is the outermost layer of the meninges, lying directly underneath the bones of the skull and vertebral column. It is thick, tough and inextensible. Within the cranial cavity, the dura contains two connective tissue sheets: Endosteal layer – Lines the inner surface of the bones of the cranium.
