serotonin
The substance that is released at an axonal ending to propagate the nerve impulse to the next nerve or muscle is called
neurotransmitters
After the neurotransmitter is released from the nerve terminal, it moves across the synapse. At that point, the neurotransmitter may bind with receptors.

ACETYLCHOLINE
Acetylcholine is the main neurotransmitter released at the effector organ when the parasympathetic division is stimulated.
Acetylcholine
A neurotransmitter.
seratonin
The small space between two neurons where neurotransmitter molecules are released is called the synapse.
You do not have single neurotransmitter, which is released from axon terminals. There are many. Some facilitate the conduction of the impulse and others inhibit the same. You have acetylcholine, norepinephrine, dopamine and many others acting as neurotransmitter.
