Final answer:

The action potential is non-decremential, maintaining its strength as it moves down the axon, due to the regenerative function of voltage-gated ion channels.

Step-by-step explanation:

The statement 'An action potential is considered to be decremential as it travels along the axon' is false. An action potential is not decremential; instead, it maintains its amplitude as it propagates along the axon. This is due to the regenerative nature of voltage-gated ion channels that actively replenish the action potential at each segment of the axon. In unmyelinated axons, this happens in a continuous wave, whereas in myelinated axons, the action potential jumps between the nodes of Ranvier in a process known as saltatory conduction, which is faster than the continuous propagation in unmyelinated axons.
