WebNeuromuscular transmission (NMT) is a process that permits the central nervous system to control the movement of muscles in the body. Nerve impulses cause the release of a neurotransmitter, acetylcholine (ACh), into the junction between the nerve cell and the muscle cell. Diseases involving the neuromuscular junction are called NMT disorders ...

WebI think we have a decent idea of how a signal is transmitted along the neuron. We saw that a couple of dendrites, maybe that one and that one and that one, might get excited or triggered. And when we say it gets triggered, we're saying that some type of channel gets opened. That's probably the trigger.
