Acetylcholine released by the parasympathetic nervous system stimulates muscarinic receptors and triggers the secretion of serous saliva. We found that intraperitoneally injected pilocarpine, which is known as a cholinergic muscarinic receptor agonist and a sialogue, increases not only saliva secretion but ...
the function of the sympathetic nervous system is to mobilize the body for action; the phrase often invoked to describe it is fight-or-flight. The function of the parasympathetic nervous
1. Acetylcholine (Ach) release from parasympathetic ganglia cell somata was investigated in denervated avian ciliary ganglia. Three days after the input to the ganglion (the oculomotor nerve) was sectioned, all presynaptic nerve terminals had degenerated. 2. Denervated ganglia were shown to ...
negatively regulate immune function by suppressing the expression of nicotinic receptors in lymphocytes. Furthermore, in vitro stimulation of muscarinic and nicotinic receptors causes functional and biochemical changes in immune cells. It is therefore likely that acetylcholine released from parasympathetic choli...

Acetylcholine is a neurotransmitter that acts within the central and peripheral nervous systems. It is the chief neurotransmitter of the parasympathetic nervous system, which contracts smooth muscles, dilates blood vessels, increases bodily secretions, a
Norepinephrine, released by sympathetic nerves in the heart, and epinephrine, released by the adrenal gland, increase the heart rate, whereas acetylcholine, released from parasympathetic nerves,decreases it. How does ACh inhibit cardiac muscle?

At many places, the acetylcholine is released in the autonomic nervous system. At the pre and post parasympathetic neurons, acetylcholine is released. Also, in all the sympathetic neurons, acetylcholine is released. Other than this, it is also released in the sweat glands. It is also released ...
(neuromuscular junctions); preganglionic neurons in both divisions of the autonomic nervous system; parasympathetic postganglionic neurons; and a few sympathetic postganglionic neurons. ACh is synthesized from choline and acetyl CoA by the mitochondrial enzyme choline acetyltransferase. Cholinergic receptors...
