WebRelease of acetylcholine is initiated by influx of Ca2+ions through voltage-operated N- or P-type calcium channels. The increased intracellular Ca2+ions bind to a vesicle-associated protein (synaptotagmin) which favors association of a second vesicle protein (synaptobrevin) with one or more proteins in the plasma membrane of the nerve terminal. Web26 nov. 2024 · The acetylcholine receptors are present in the walls of postjunctional folds. These receptors are also called cholinergic receptors.
