WebThe “All-or-none law” is a theory that states that a nerve cell or muscle fiber strength of the response is not contingent on the strength of the stimulus. A nerve or muscle fiber can exciter become activated if a stimulus is above a required threshold value. As a result, for an isolated neuron or muscle fiber, there will be a complete ...
