You use a short period electrical stimuli to observe muscle fibers contracting continuously (tetanus).Chemical agents can cause tetanus by interfering with the motor neurons. These agents include atoxin produced by the soil bacterium Clostridium tetani. One of the symptoms of these agents iscalled 'spastic paralysis'! Explain in your own words why these agents would be a bad thing for youand your muscles.
