WebJan 24, 2011 · This is how action potentials are propagated along the length of the axon. The inability of Na+ channels to re-open after the first action potential was fired ensures … WebAction potentials are usually generated at one end of a neuron, typically the cell body, or soma, and then "propagated" like a wave along the axon towards the opposite end of the neuron. The image below shows how an action potential might have started near the cell soma (notice the depolarization in 1A) and as it propagates down the axon towards the …
