Expert Answer
Characteristics of a Local potential versus an Action potential are given below in the table:

Action potential Local potential Local potential is graded, that means it vary in voltage according to strength of the stimulus. A prolonged stimulus opens more ion gates than a weaker one They are decremental, that means they get weaker as spread from the point of stimulus. stimulus causes ion channels to open, results in increased membrane Generation of action potential follows All or None principle. Refractory period lasts from the time action potential starts until normal resting potential returns. It triggered by depolarization. And it is initiated at an axon hillock. permeability to sodium (Na), potassium (K*) or chloride (Ch) ions. Increased membrane permeability to Na causes depolarization. While increased membrane permeability to K* or Clions causes hyperpolarization. It understands repolarization, depolarization, and hyperpolarization.
Local potential: It occur in any region of the cell membrane, however in neurons. It also occurs in specialized regions of synapse involved ...
