Which of the following is the best analogy of propagation of the action potential?
A) a series of dominoes falling down
B) the telephone-game where one person tells the next a message
C) a gun firing
D) a chain letter

Question

The propagation of the action potential is best compared to a series of dominoes falling down because just like how each domino falling triggers the next one to fall, the action potential traveling down the axon triggers the opening of voltage-gated ion channels and the movement of ions, which in turn triggers the next section of the axon to depolarize and send the action potential in the forward direction.
