For minor surgeries in the body, doctors administer local anaesthesia to a part of the body so that the pain will not be felt by the patient. At which part, do you think, the nerve impulse is being arrested due to the effect of anaesthesia?
A. at cyton

B. at axon

C. at synapse

D. in the middle of axon

Answer :

Because synapse is the site from where the transmission of the impulse takes place. When the impulse of transmission is arrested the signal does not reach the brain and we do not feel any pain and sensation. Therefore anesthesia acts on synapses.
