How does electrical impulse in the neuron change into chemical impulse in the synapse?

The dendrite end of the neuron collects information and triggers a chemical reaction, which results in an electric impulse. This impulse is transmitted from the dendrite to the cell body and then to the axon. From the axon, the impulse travels to its end (synapse), where the electrical impulse sets off the release of some more chemicals (neurotransmitters). These chemicals cross the synapse and start a similar electrical impulse in the dendrite of the next neuron. In this way, electrical impulses are transmitted from one neuron to another through these chemicals and these finally reach the brain. Thus, electrical impulse in the neuron change into chemical impulse in the synapse by chemical called neurotransmitter.

In a neuron in the end from where the chemical is relesed there neurotransmitters are present which converts electrical impulse in chemical (Acetyl choline) which is recieved by neurotransmitters receptors and then carried to cell body there it again converts to electric impulse.

Hope this helps :-]

Receptors are present at the dendritic tip. The information is collected at this dendritic tip. A chemical reaction sets off at the dendritic tip which converts it to electrical impulses. This electrical impulse then travels to the axon through the cell body. From the axon, it goes to the nerve ending and sets off the release of some chemicals at the synapse which crosses the synapse and passes on to the next nerve cell. This is how information passes from one nerve cell to the other.
