Question
The purpose of an action potential (AP) is to propagate a signal down the axon to the axon terminal. What happens once it reaches the axon terminal? Using the experiment showing recordings from the post-synaptic cell (endplate potentials), describe what happens when an AP reaches the axon terminal and subsequently transmits the signal to a neighboring cell. What does this tell us about chemical neurotransmission?
