Web5 mrt. 2024 · Multiple Sclerosis: Overview. Within this disease, the myelin is destructively removed from around the axon which slows down nerve impulses. As axons are demyelinated, these result in inflammatory patches called lesions and it is thought that this disorder is an autoimmune disease. As the disease progresses, oligodendrocytes and, … Web8 mei 2024 · Function In both peripheral and central nervous systems, myelin plays a crucial role in the protection and conduction of many neurons. Myelin sheath acts as an insulator allowing for protection of the integrity of the nerve impulse as well as protecting the axon from foreign electrical impulses.
