myelinated
Axon has covering
Myelinated describes nerve fibers that are covered with myelin, a fatty insulating sheath that allows electrical impulses to travel faster along the nerve.
The term appears almost exclusively in medical and biological contexts.
Myelinated axons conduct signals more efficiently than unmyelinated ones.
Diseases like multiple sclerosis damage the myelin coating, disrupting neural communication.
