At rest, voltage-gated Na+ and K + gates are closed. 2. Chemical or mechanical stimulus causes a graded potential to reach at least (-55mV or threshold) This is "depolarization" 2.

WebSep 21, 2009 · Wayne, The all-or-nothing principle only refers to the discharge of action potential by a motor neuron; either it discharges an action potential or it does not. It is not correct to apply this principle to the force generated by a muscle fiber, which depends on the action potential-mediated level of calcium within the fiber.
WebThe all-or-none principle is for the "response" to a stimulus. The stimulation strength can be different, only when the stimulus exceeds the threshold potential, the nerve will give a complete response; otherwise, there is no response.
