ANSWER: Action potential occurs when a membrane potential of a specific cell location rapidly rises and falls, this depolarisation causes adajacent location similarly to depolarise. It is generated in the body of neuron and is propagated through the axon from one neuron to another. The action potential is fastly conducted in the mylineated axon by saltatory conduction. In saltatory conduction the action potential junls from one node of Ranvier to another node of Ranvier. The depolarisation is due to opening of voltage gated sodium channel and the influx of sodium ions. Then slowly the potassium channel opens anf efflux of ions haplens resulting in Hyperpolarisation of the neuron.
