Where the electric impulse is converted into chemical signal for onward transmission Ina neuron?
I think you have your question backwards.Chemical signal comes before electrical impulse, not vise versa, unless you are referring to pre/post synaptic communication. Since I don’t really know which part you are trying to ask about, I’ll just explain the whole entire process. When a nervous signal is sent, an electrical impulse is sent down the axon of a pre-synaptic neuron. The impulse stimulates teh vesicle sacs in the axon terminal. The stimulation causes the vesicles to release the neurotransmitters into the synapse between the pre-synaptic cell, and the post-synaptic cell. After the neurotransmitters cross the synapse, they stimulate the dendrites of the post-synaptic neuron. The stimulation causes specific receptor protein ion channels to open and become activated. This causes an influx of whatever ion the receptor channel is supposed to be able to process. Then the sodium ions rush through the cell membrane, causing a change of polarity. It will either cause a depolarization wit
