Meninges are three membranes layers that cover and protect your brain and spinal cord (central nervous system). These membranes — the dura mater, arachnoid mater and pia mater — protect and anchor your brain and provide a support system for blood vessels, nerves, lymphatics and the cerebrospinal fluid that surrounds your central nervous system.
The spinal cord is a single structure, whereas the adult brain is described in terms of four major regions: the cerebrum, the diencephalon, the brain stem, and the cerebellum. A person’s conscious experiences are based on neural activity in the brain.

Oct 22, 2024 · What are the other structures of the spinal cord? Your spinal cord is covered in layers of tissue called meninges (just like the ones that surround your brain). These protective tissues include: Dura mater: The outer layer that protects your spinal cord from injury. Arachnoid mater: The middle layer. Pia mater: The deepest inner layer.
Layers of connective tissue called meninges support and stabilize the brain and spinal cord, as well as partition the brain into specific regions. The outer layer is the dura mater, the middle layer is the arachnoid mater and the inner layer is the pia mater.
Nov 3, 2023 · The function of the meninges is to protect the brain and spinal cord from mechanical trauma, to support the blood vessels and to form a continuous cavity through which the cerebrospinal fluid (CSF) passes.
Jun 2, 2021 · The meninges refer to the membranous coverings of the brain and spinal cord. There are three layers of meninges, known as the dura mater, arachnoid mater and pia mater. These coverings have two major functions: Provide a supportive framework for the cerebral and cranial vasculature.
Your central nervous system looks like a balloon. Your brain is the round, inflated balloon. Your spinal cord is the string attached to the balloon. Your brain and spinal cord are held within bone structures, connective tissue (meninges) and fluid (cerebrospinal fluid), which protects them.
