What happens to an action potential when it comes to one of the nodes of Ranvier?
A) The action potential jumps from node to node, which is how it moves down the axon with great speed.
B) The action potential gets rebounded back to the soma, where it has to be re-established.
C) The action potential dissipates and fails to make it to the next neuron, which is why illnesses that cause the nodes of Ranvier are so devastating.
D) The action potential causes neurotransmitters to be released from the node.
