The tetanus toxin affects the site of interaction between the nerve and the muscle that it stimulates.This region is called the neuromuscular junction.The tetanus toxin amplifies the chemical signal from the nerve to the muscle, which causes the muscles to tighten up in a continuous (tetanic or tonic) contraction or spasm.This results in either localized or generalized muscle spasms.he tetanus toxin amplifies the chemical signal from the nerve to the muscle, which causes the muscles to tighten up in a continuous (tetanic or tonic) contraction or spasm.
