The central nervous system, being made up of the brain and spinal cord, is crucial for communication throughout the body. In a properly functioning central nervous system, there are neurons that assist in this communication be perceiving and sensing information, then sharing it with the brain, allowing the body to make functional movements. Neurons are made up of axons (nerve fibers), dendrites, and a cell body. The dendrites receive information and the axons then send the information back to the brain or spinal cord by what is called nerve impulses (Butler, Lewis, Shier, 2013, p. 363). The axons are coated with myelin, which is made up of proteins and lipids that protect the axons or nerve fibers. (Butler et al, 2013, p. 365). This communication allows the brain to tell other parts of the body (like muscles) what to do and when to do it, providing the body with normal functioning for the everyday movements that must occur. Damage to this perfect balance can alter how the body moves and functions.
Multiple Sclerosis (MS) is a progressing condition where the communication between the brain, spinal cord, and other parts of the body has been destroyed. It is thought to be a disease of the immune system, where it actually attacks the body’s central nervous system, although the exact substance within the immune system that causes this condition has yet to be determined (National Multiple Sclerosis Society). The myelin that surrounds the nerve fibers is destroyed, leaving them…
