SYNAPSE

=SYNAPSE is the space between two neurons through which the nerve impulse is transmitted. Two neurons are never in touch.= =When one neuron produces a nerve impulse (which is an electrical signal), it travels along the axon of the neuron.= =When the impulse reaches the end branch of the neuron, it stops, and chemical messengers called neurotransmitters come= =out of this first neuron. Neurotransmitters cross the synapse gap and reach a dendrite of a second neuron. When this neuron= =receives the neurotransmitters, it generates the same nerve impulse as the first neuron, and the process starts again.=
