Propagation of Action Potential has to do with unmyelinated axons, when they do have Myelination the process of propagation is different. When the axons have myelination they send the charge even faster than without because it is being conducted and given a boundary that the charge with not get last through and will go one way together. Not only through myelination but also the diameter of the axon, the bigger the axon the quicker the action potential will travel through. The action potential are transmitted while you go down the axons because the Na+ channels are being opened up and depolarization is becoming more apparent in the cell. The voltage gated Na+ channels can’t stay open for ever and need a recovery time so they are always opening new Na+ channels to get the Na+ ions further in. The propagation always has to happen at the axon terminals because of this recovery time, and the constant need for the voltage so that the ion channels can open. There has to be another stimulus in the axon hillock to get the Action potential to shoot off a create a voltage to open the
