Quizplus · Accepted Answer

When neurotransmitters communicate an excitatory message to the postsynaptic neuron, the postsynaptic neuron is more likely to generate an action potential, which can lead to the transmission of the signal to other neurons or effector cells. Excitatory neurotransmitters such as glutamate, acetylcholine, and norepinephrine can depolarize the postsynaptic membrane, which may trigger an action potential if the threshold is reached.
