WebJan 17, 2024 · Nicotinic acetylcholine receptors are receptors found in the central nervous system, the peripheral nervous systems, and skeletal muscles. They are ligand-gated ion channels with binding sites for acetylcholine as well as other agonists. When agonists bind to a receptor it stabilizes the open state of the ion channel allowing an influx of cations.
