WebJan 25, 2024 · Nerve impulse refers to the temporary changes in the neuron due to the disturbance created by the stimulus of adequate strength. This nerve impulse propagates through the Axon, synapse and, neuromuscular junction is called Nerve Impulse conduction. Diagram Fig: Generation and Conduction of Nerve Impulse WebIons are not supposed to migrate back towards the soma (neuron cell body). This is mainly due to the refractory period. It is period of time after an action potential occurs at one point of the axon when it is impossible to produce another action potential at this point. So, ions cannot go backward because they would diffuse passively and ion ...
