How Myelin Affects The Body 's Immune System Targets The Central Nervous System

Multiple sclerosis, or MS, is an autoimmune disease in which the body’s immune system targets the central nervous system (National Multiple Sclerosis Society, 2016). The central nervous system is mainly made up by the brain, nerves, spinal cord, and optic nerves (National Multiple Sclerosis Society, 2016). The main target in MS is myelin, the substance that protects the nerve fibers within the central nervous system (National Multiple Sclerosis Society, 2016).
By attacking the myelin MS causes inflammation and damage to the myelin itself (MS Society of Canada, 2016). Myelin is the main source of transportation for nerve impulses; this is done through the nerve fibres that are protected by the myelin (MS Society of Canada, 2016). If the myelin is only slightly damaged the nerve impulses can continue with a few minor interruptions, but if the damage is extensive then problems become more apparent (MS Society of Canada, 2016).
When myelin is quite damaged it begins to turn into scar tissue; scar tissue does not transmit nerve impulses as myelin does (MS Society of Canada, 2016). This means that once the myelin becomes scar tissue, the nerve impulses become completely interrupted (MS Society of Canada, 2016). This complete interruption in the nerve impulse process can then lead to the damaging of the nerve fibres themselves (MS Society of Canada, 2016).
Causes of Multiple Sclerosis: There has not been a specific cause of MS identified, but it has been thought that a wide
