What is Myelin?
As part of the nervous system, myelin lines nerve fibers to protect and insulate neurons. Myelin aids in the quick and accurate transmission of electrical current carrying data from one nerve cell to the next. When myelin becomes damaged, the process involves numerous health conditions, including multiple sclerosis. Nerves are like an electrical wire. Current (the message) must be conducted along a path (the nerve) to successfully get from point A to point B (the brain to a fingertip). The electrical current must travel without being corrupted, scrambled, diverted from the proper path, or leaking energy. Therefore, myelin is like the layer of plastic insulation surrounding an interior wire, which is the nerve. Additionally, myelin speeds the conduction, so it’s also analogous to a secondary coating on the wire that reduces the resistance facing an electrical current. The interior wire represents the series of axons and nerve cells that relay the electrical impulse. Myelin is always mad
