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 ... WebWhen the nerve impulse reaches the end of the axon, there are some chemicals released from the neurotransmitters.

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. how to scan to pdf on windows

"WebA nerve impulse is transmitted to another cell at either an electrical or a chemical synapse . At a chemical synapse, neurotransmitter chemicals are released from the presynaptic cell into the synaptic cleft between cells. The chemicals travel across the cleft to the postsynaptic cell and bind to receptors embedded in its membrane. " - How is a nervous impulse transmitted

WebA nerve impulse is an electrical signal that travels along an axon. There is an electrical difference between the inside of the axon and its surroundings, like a tiny battery. When the nerve is activated, there is a sudden change in the voltage across the wall of the axon, caused by the movement of ions in and out of the neuron.
