Kindly explain how the synapse passes the nerve impulses from one axon terminal to the dendrite of the next neuron. Please explain this in detail with a diagram.

Dear student, 

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.

Observe the flow diagram given below :-




The diagram shows propagation of nerve impulses from one neuron to next and then from a neuron to muscle. The first picture shows the propagation of nerve impulses from dendrite of one neuron to axon of the next. While, the second picture shows the location of synapse and third and fourth illustrates the synapse.


Regards
