Question

Quizplus · Accepted Answer

Myelin is a specialized cell membrane that wraps around axons in the peripheral and central nervous systems to facilitate conduction of action potentials. Diseases that destroy myelin impair this conduction, leading to various symptoms. Examples of such diseases include multiple sclerosis, leukodystrophies, and neuromyelitis optica. These diseases are not restricted to the central nervous system, and they do not destroy astrocytes or tripartite synapses. While some treatments exist to manage the symptoms of these diseases, there is currently no cure for myelin destruction.
