The tetanus toxin tetanospasmin blocks release of the neurotransmitter (GABA)that inhibits motor neurons and decreases muscle contraction.This causes persistence of the signal to contract and the resulting violent muscle contraction known as tetanic spasm.Compare the sustained contraction of muscle cells in rigor mortis with muscle contraction caused by the action of tetanospasmin on motor neurons.
