Expert Solution

Step 1 Introduction on few terms:

The Neuron's membrane consists of sodium to be present in large quantity in the extracellular part and potassium and other negative charged proteins in the interior of the neuron cell membrane. The myelinated sheath is an extension of oligodendrocyte and Ranvier's Node are the area for sodium gated channels for saltatory conduction to operate in the myelinated axon. When a particular threshold is reached, then only the action potential is generated. The potassium channels are always open, also known as leak channels are simply non gated channels, that leads to the hyperpolarization effect in the neurons.
