Action potentials are generated in the axon.These so-called trigger areas are generally a response to accumulated actions generated due to membrane potential reaching a threshold app. -55mV a depolarization of about 15 mV.This leads to a self propagating action in the axon transmitted to the peripheral neurons through synaptic receptors.This overlapping action potential are opening and closing of ion gates and subsequent changes in membrane potentials.
