myelin
Axon's fatty coating
Myelin is the fatty substance that forms a protective sheath around nerve fibers, enabling rapid transmission of electrical impulses.
The myelin sheath acts as insulation, much like the coating on electrical wire.
Damage to myelin disrupts nerve signaling and underlies conditions like multiple sclerosis: The disease attacks the myelin surrounding nerves in the brain and spinal cord.
