MECHANISM+OF+HEARINGSYNAPSEINVOLUNTARY+RESPONSES+OR+REFLEXES

= 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. =
