Does an entire muscle give an all or none response?
The all-or-none law is the principle that the strength by which a nerve or muscle fibre responds to a stimulus is independent of the strength of the stimulus. If that stimulus exceeds the threshold potential, the nerve or muscle fibre will give a complete response; otherwise, there is no response.Click to see full answer. Also…

Also asked, what is the all or none response in muscles?The all-or-none law is a principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fiber will fire.Beside above, what is an all or nothing action potential? An action potential occurs when the membrane depolarises to a certain threshold, if this threshold is not reached the action potential will not be triggered. This is referred to as the all-or-nothing principle in biology: it means that the power of a stimulus is not proportional to the power of the action potential. Similarly one may ask, why is an action potential an all or none response? There are no big or small action potentials in one nerve cell – all action potentials are the same size. Therefore, the neuron either does not reach the threshold or a full action potential is fired – this is the “ALL OR NONE” principle. Action potentials are caused when different ions cross the neuron membrane.What is all or none law in physiology? noun Physiology. the principle that under given conditions the response of a nerve or muscle fiber to a stimulus at any strength above the threshold is the same: the muscle or nerve responds completely or not at all.
