Question

How does nerve impulse travel?(its urgent)

Answer 1

The electric signals are transmitted from one neuron to next and to the muscles across a synapse through the release of chemicals called neurotransmitters. The axon terminal of nerve fibres contain synaptic vesicles filled with these neurotransmitters which are released in the gap called synapse. The released neurotransmitters reach to the next neuron causing changes over their and start a similar electrical impulse in a dendrite of the next neuron or action in the muscle.
