Due to the presence of the insulating myelin sheath at internodes and voltage-gated sodium channels at nodes, the action potential in myelinated nerve fibers jumps from one node to the next.

Myelin is an insulating layer of lipids and proteins surrounding nerves. Myelin damage can cause problems with the nerves’ ability to send and receive electrical messages. Inflammatory disorders ...
