Question

What is a synapse? How does a nerve impulse travel from one to another neuron?

Answer 1

• A synapse is a gap between two neurons. 
• The nerve impulse or neural message jumps across the synapse in order to reach the dendrite of another neuron. 
• When the neural message is passing through, it excites or inhibits the neurotransmitter in it. This chemical reaction decides our reaction to various situations.
