What is the purpose of the myelin insulation?

Explanation:
Myelin’s job is to insulate the axon and protect the nerve connection. It wraps around the axon in segments with gaps called nodes of Ranvier, so the electrical signal can hop from node to node. This insulation reduces leakage of current and makes it faster to reset the ion balance after a signal fires, which greatly speeds up how quickly the message travels along the neuron. It doesn’t change how neurotransmitters are produced, it doesn’t store electrical energy, and it doesn’t create new synapses.
