Vedclass · Answer

(A) Tetanus is caused by the bacterium $Clostridium$ $tetani$.This bacterium produces a potent neurotoxin called tetanospasmin.This toxin travels to the central nervous system and blocks the release of inhibitory neurotransmitters (like glycine and $GABA$).As a result,the motor neurons become overactive,leading to continuous,painful spasms and contractions of the voluntary muscles.Therefore,the toxin primarily affects the voluntary muscles,causing symptoms like lockjaw and muscle rigidity.
