That is impulse jumps from … WebHow is a nerve impulse transmitted from one neuron to another? When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. ... The binding allows the nerve impulse to travel through the receiving neuron.

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.
