How is a nervous impulse transmitted

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 you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.”. Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.

Web25 mrt. 2024 · synapse, also called neuronal junction, the site of transmission of electric nerve impulses between two nerve cells (neurons) or between a neuron and a gland or muscle cell (effector). A synaptic connection between a neuron and a muscle cell is called a neuromuscular junction. 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.
