Question

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. First, explain the series of events for a normal muscle contraction (this will be a long answer – you can list the steps in bullet form and you do not have to use complete sentences. Now explain where/how the action of tetanospasmin will affect muscle contraction. Finally, explain where the effects of rigor mortis happen in your muscle contraction answer.
