How does the presynaptic axon respond to the action potential?

1 Answer

Chemical transmitters are released as a result of an action potential in the presynaptic terminal.

An action potential is generated at the axon hillock (motor neuron) or the first node of Ranvier (sensory neuron).

Explanation:

A potential change in the presynaptic cell releases transmitter that produces a postsynaptic potential.
