When a stimulus is applied to a receptor in the skin, an action potential is propagated along a neuron to the brain, where another signal is sent back to the muscle for a response.

Which of the following best describes what occurs when the action potential reaches a chemical synapse at the end of an axon?

Cells communicate through chemical signals. Neurotransmitters are released from one cell and transferred to another. The area between two neurons is called the synapse.

Action potentials do not jump or travel from neuron to neuron directly.
