All or none law is obeyed by: March 2005
Ans. C: Action potentialOnce threshold intensity is reached, a full fledged action potential is produced.The action potential fails to occur if the stimulus is subthreshold in magnitude and it occurs with constant amplitude and form, regardless of the strength of the stimulus if the stimulus is at or above threshold intensity. Therefore action-potential obeys all or none law
Post synaptic potential
Non propagated potential
Action potential
Spike potential
