WebA nerve impulse is an all-or-nothing response depending on if the stimulus input was strong enough to reach threshold. If a neuron responds at all, it responds completely. A greater stimulation does not produce a stronger impulse. Figure 8.4.2 An action potential speeds along an axon in milliseconds. WebSolution. Information is received by the dendrite tip of the nerve cell. Sets off a chemical reaction and creates an electrical impulse. The electrical impulse will travel to the neuron cell body. From the cell body to the ends of the axon through the axon. The electrical impulse causes the release of chemicals by the ends of the axon.
