WebMany vertebrate neurons are protected by a myelin sheath made of Schwann cells that are connected to axons. They are in charge of creating the myelin sheath, which aids in insulating and hastening the transmission of nerve impulses. A fatty layer called the myelin sheath protects and insulates the axon by covering it. WebIn people with MS, the immune system attacks cells in the myelin, the protective sheath that surrounds nerves in the brain and spinal cord. Damage to the myelin sheath interrupts nerve signals from your brain to other parts of your body. The damage can lead to symptoms affecting your brain, spinal cord and eyes.
