Acetylcholine (ACh) is a neurotransmitter, a chemical that carries messages from your brain to your body through nerve cells. It’s an excitatory neurotransmitter. This means it “excites” the nerve cell and causes it to “fire off the message.” Acetylcholine gets its name from the two substances that it’s made from — an … See more An enzyme called choline acetyltransferase causes a reaction between choline and the acetyl group to create acetylcholine. It’s made at the end of nerve cells. See more Acetylcholine is found in your central nervous system (CNS), your brain and spinal cord, as well as in your peripheral nervous system(the nerves that branch out from your CNS and … See more Acetylcholine is stored at the end of nerve cells until it’s triggered to be released. Once released from the end of the nerve cell, it moves into a … See more Acetylcholine has many roles. When it binds to muscarinic receptors, it: 1. Regulates heart contractions and blood pressure and decreases heart rate. 2. Moves food through … See more WebMar 21, 2024 · Acetylcholine and Endothelial Function. Hasdai et al 1 reported that myocardial perfusion defects are produced in response to acetylcholine 10 −4 mol/L IC. However, acetylcholine has dual effects on coronary artery tone depending on the intracoronary concentration of acetylcholine and the presence of coronary atheroma.
