How does the Action Potential Work?
Action potential is nerve impulse. The best known actions of these impulses are wave-like pulses of voltage traveling along the axons of neurons. Read More »

What are the events in an action potential?
As sodium ions diffuse inward, the membrane loses its negative electrical charge and becomes depolarized. At almost the same time, however, membrane channels open that allow potassium ions to pass through, and as these positive ions diffuse... Read More »

A.P. propagation consists of the movement of the action potential along the axon, axon terminals and dendrites. A.P. propagation is non-decremental meaning that the amplitude of the A.P. remains constant throughout the propagation. Action p...

The reason why cardiac muscle has a longer action potential is to extend the absolute refractory period to prevent another action potential. If too many action potentials stimulate the cardiac muscle it can get into tetanus which keeps the ...
