Meninges. That’s where the name meningitis comes from, it refers to inflammation of the meninges that cover and protect the brain and spinal cord.
Damage to the meninges is not a cause of MS however. Myelin is the coating of individual nerve cells which deteriorates in MS. When that happens, the electrical signals travel more slowly along the nerve cell fibers. Meninges on the other hand cover and protect the entire brain and spinal cord which are made up of 100 billion nerve cells!
The brain and spinal cord are covered by a tough, translucent membrane, called the dura matter. Cerebrospinal fluid (CSF) is a clear, watery liquid that surrounds the brain and spinal cord, and is also found throughout the ventricle (brain cavities and tunnels). CSF cushions the brain and spinal cord from jolts.
