Expert Answer
- Synapse allows a neuron to pass the nerve impulse to the adjacent neuron.
- Synapse is a chain of several processes. When pre-synaptic neuron pass the nerve impulse to the axon terminals at their ends, the axon terminal secrete neurotransmitters.
- These neurotransmitters carry the impulse in the form of chemical signal to the adjacent neuron.
- There are binding sites present at the dendrites of the post-synaptic neuron to which these neurotransmitters bind to release or send the impulse further.
- At the same time a single neuron may have synaptic connections with several neurons at a time. Presence of synapse makes it easy for a neuron to interact with several neurons at a time.
