Answer:
When the nerve impulse reaches the dendrites at the end of the axon, chemical messengers called neurotransmitters are released. These chemicals diffuse across the synapse (the gap between the two neurons). ... The signal therefore has been carried from one neuron to the next.

The nerve impulse is transmitted from one neuron to the next through a gap or cleft called a synaptic gap or cleft or a synapse by a chemical process. Synapses are specialized junctions through which cells of the nervous system communicate to one another and also non-neuronal cells such as muscles and glands.
