Myelin:Myelin is a fatty substance produced by specialized cells called oligodendrocytes in the central nervous system (CNS) and Schwann cells in the peripheral nervous system (PNS). It forms a protective coating around certain axons and helps facilitate rapid conduction.
Conduction Velocity: Conduction velocity refers to how fast an electrical impulse travels along an axon. The presence of myelin and jumping between nodes contribute to increased conduction velocity.
Demyelination: Demyelination is the loss or damage to myelin sheaths surrounding nerve fibers. It can result in impaired neural communication and is associated with various neurological disorders, such as multiple sclerosis.
