Multiple Sclerosis
Multiple Sclerosis (MS) is a disease of the central nervous system (CNS). The CNS is made up of the brain and spinal cord. The CNS nerves are made up of single neurons that are responsible for carrying messages from the brain. Each neuron is made up of a nucleus, dendrites, axon, cell body and a covering called the myelin sheath.

The myelin sheath protects the nerve (axon) from damage. In MS, the body's own defences (t-cells) attack the myelin, the substance that protects the nerve fibers of the brain, optic nerves, and spinal cord.
