Nerve Impulse - A nerve impulse can be described as the electrical signal that transmitted along with a nerve fibre.

 The electrical impulse travels from dendrite to the cell body and then along the axon. At the axonal end, electrical signals release chemical substance, which crosses the synapse to the next neuron.
