Question

Quizplus · Accepted Answer

The movement of the action potential occurs along the axon at the nodes of Ranvier. These are the small gaps in the myelin sheath that surround the axon. When the action potential reaches a node of Ranvier, it triggers the opening of voltage-gated ion channels, allowing ions to flow in and out of the axon, which propagates the signal down the axon. The movement of the action potential does not occur along the dendrites or on the cell body, and it does not occur between neurons at the synapse, where neurotransmitters are released.
