How is an action potential propagated?
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... Read More »

Why is action potential propagation unidirectional?
Simple answer: Because a segment of the axon membrane that just triggered an action potential cannot generate one for a short period of time - that segment has to recover. But the segment next in line can generated an action potential. More... Read More »

How do action potentials propagate?
Consider the axon as a series of transverse slices and consider that the AP is in one slice. Na enters the cell and, yes, flows down the axon to the slice #2 (we really should say the current flows). This will depolarize slice #2 causing an... Read More »
