How does myelin aid propagation of an action potential
along an axon? How do the nodes of Ranvier help this
process?
Action potential refers to a change in the membrane potential of the nerve cells by opening and closing several ion channels for the propagation of the nerve impulse from one neuron to another neuron. This propagation of the action potential helps in transporting the signal from any part of the body to the brain and action potential also helps in the contraction and relaxation of the muscle. Action potential propagation does not diminish or influence the nature of the impulse in any manner so that the objective cell receives a similar type of impulse regardless of how distantly they are from the neuronal body.
