How does acetylcholine get released
WebMay 8, 2024 · The release of these hormones into the bloodstream is stimulated by acetylcholine (released from preganglionic splanchnic fibers) which binds nicotinic receptors located in the adrenal medulla. ... to bind … WebWhen a neurotransmitter binds to its receptor on a receiving cell, it causes ion channels to open or close. This can produce a localized change in the membrane potential—voltage across the membrane—of the receiving cell. In some cases, the change makes the target cell more likely to fire its own action potential.
