How does electrical impulse travel through the neuron? What chemical reaction takes place between the dendrites and nerve ending. Pls answer fast

hii..
Electrical impulse doesnt need any neurotransmitter for its conduction as there is no synapse b/w axon and dendrite so the electrical travels just as a normal impulse as in axons..
In chemical transfer neurotransmitter like acetylcholine are involved..
Due to the depolarisation in axon endings..Ca+ channels open and Calicium rushes in the synaptic knob...it pushes the synaptical vesicle to pre-synaptic membrane..synaptic vesicle has neurotransmitter..
After the fusion of synaptic vesicle it releases neurotransmitter into the synapse which further conducts the nerve impulse to dendrites of the another neuron..
hope this helps!!

electric impulse don't need chemical reactions but it required some potential difference on its membrane and on synapses they require different neurotransmitter in chemical synapses in signal transfer through neurons to next neuron
