The "all-or-none law" states that an action potential either fires at full strength or not at all. In other words, the neuron either reaches its threshold and fires an action potential, or it does not fire one at all. It is not dependent on the activation of all dendrites or neurons in a nerve, nor is it affected by whether all axon terminals are in a refractory period.
