Final answer:
Axoplasmic transfer, specifically saltatory conduction between nodes of Ranvier, recycles the action potential and allows for faster signal propagation.
Step-by-step explanation:
The recycling of the action potential in axons is achieved through a process called axoplasmic transfer.
During axoplasmic transfer, the action potential is regenerated at each node of Ranvier along the myelinated axon.
The action potential jumps between nodes of Ranvier, a process known as saltatory conduction, which allows for faster propagation of the signal.
