Question

Discuss action potential and the all-or-none law. Compare the function and process of the refractory period, including the relative and absolute refractory periods

Answer 1

Introdution :-

Action potential :- Action potential occurs when potential membrane of every axon location rapidly rises or fall, as an action potential nerve impulse travels down an axon there is change in polarity across the membrane of axon. In a response to a signal from another neuron sodium and potassium.

All or none law :- The all -or -none principle is about nerve and muscle fibres is independent of the strength of the exciting stimulus. In which there nerve and muscles and give full response neither no response.

Comparision and process of:-

Refractory period :- Refractory period is immediately following stimulaton during which a nerve or muscle is unresponsive to further stimulation.
