it acts as just a neurotransmitter for both the central nervous system and the peripheral nervous system
acetylcholine
Neurotransmitters are the substances found in synaptic vesicles of axon terminals. These neurotransmitters are released into the synapse, where they transmit signals from one neuron to another. Some common neurotransmitters include dopamine, serotonin, and acetylcholine.
The two main neurotransmitters released by the axon terminals of autonomic neurons are acetylcholine and norepinephrine. Acetylcholine is predominantly released by parasympathetic neurons, while norepinephrine is released by sympathetic neurons.
A neurotransmitter is either taken up by the presynaptic terminus or digested/cleaved in the synaptic cleft. For example Acetylcholine is cleaved by a specific esterase present in the neuromuscular junction.
Along with dopamine, serotonin and norepinephrine, acetylcholine is a neural transmitter. Some substances act as mediators and others, including acetylcholine, simulate or active the next nerve cell as impulses pass down the a nerve. Once it has performed this action by passing across the synapse (neural junction between two nerve cells) it is broken down by an enzyme called acetylcholine esterase into an acetyl group and choline. Acetylcholine also passes across the neural muscular junction, similar to the synapse between neurons (nerve cells) and also between nerve endings and muscle cells stimulating them and thus causing your muscles to move. Acetylcholine is also involved in memory and learning and is in particularly short supply in people with Alzheimer's disease. A recently released drug helps Alzheimers sufferers by inhibiting the action of acetylcholine esterase.

Acetylcholine and norepinephrine.
You have acetylcholine liberated at ganglion in both sympathetic and parasympathetic nervous system. You have noradrenaline secreted at post ganglionic sympathetic nerve terminals. You have acetylcholine secreted at post ganglionic parasympathetic nerve terminals.
norepinephrine. Acetylcholine mainly causes smooth muscle contraction, while norepinephrine can either cause contraction or relaxation depending on the type of receptor it binds to on the smooth muscle cell.
chemical synapse
nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.
Answer is Neurotrasmitters. There are several hundred types of neurotransmitters in brain. Some of them are Dopamine,Serotonin,acetylcholine,Adrenaline, Nor-adrenaline, Histamine,pep-tide neurotransmitters, certain amine acids. So impulse of depolarization flows across the nerve fiber and there is closed space between junction of two nerves, where chemical substances flows across, carrying the impulses to next nerve. After impulse is given to the next nerve fiber by say acetylcholine, then it will be destroyed by the enzyme acetylcholinesterase. Nor-adrenaline is taken up back by the nerve fiber.

A neurotransmitter is a chemical messenger that transmits signals across a synapse from one neuron (nerve cell) to another target neuron, muscle cell, or gland cell. These chemicals play a crucial role in communication within the nervous system, influencing various functions such as mood, behavior, and bodily functions. Examples of neurotransmitters include serotonin, dopamine, and acetylcholine.
