Explanation:
Detailed explanation-1: -When an action potential reaches the presynaptic terminal, it causes neurotransmitter to be released from the neuron into the synaptic cleft, a 20–40nm gap between the presynaptic axon terminal and the postsynaptic dendrite (often a spine).
Detailed explanation-2: -Acetylcholine, for example, is the neurotransmitter that is released by a neuron to stimulate a muscle cell. If the axon terminal fails to release acetylcholine, there will be no chemical to activate the target muscle.
