How does myelin increase the speed of nerve impulse conduction?
The way an action potential propagates is by opening voltage-gated sodium channels which depolarize the cell. Think about how long it would take to conduct an action potential if you had to open channels along the entire length of the axon and wait for sodium influx. In the case of the myelinated nerve fibers, the myelin sheath covers large portions of the axon, leaving uncovered spaces known as nodes of Ranvier. The sodium channels in a myleinated nerve fiber are only at the nodes of Ranvier. So one sodium channel opening depolarizes a much greater length of the axon until it reaches the next node of Ranvier, where the voltage-gated sodium channels open and this cycle continues. In essence the AP "hops" around, covering much greater distance in a shorter amount of time.
