... A nerve impulse is self-propagating; that is, the flow of ions at the point of the impulse causes sodium channels just ahead of it to open. This allows the impulse to move rapidly along the axon. The flow of an impulse can be compared to the fall of a row of dominoes. As each domino falls, it causes ...
