WebSynaptic Transmission [1:51] Let us go over each step covered in that video in more detail. When an action potential arrives at the terminal, various voltage-gated ion channels are opened. Along with the usual sodium and potassium ion channels, calcium ion (Ca2+) channels are opened. WebCholinergic neurotransmission is mediated by the neurotransmitter acetylcholine (ACh). Upon release, acetylcholine (ACh) is rapidly hydrolyzed into choline and acetic acid ( Chapter 14) by a family of enzymes called cholinesterase (ChE).
