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.

1 INTRODUCTION A neuromuscular junction is a synapse between a motoneuron and a muscle cell it innvervates. The prejunctional nerve terminal is a transducer that converts an electrical signal (an action potential in the prejunctional motoneuron) into a chemical signal (transmitter release).t the neuromuscular junction (figure to the right) the terminal branch of the motor axon lies in a shallow groove, or synaptic trough, on the muscle cell. The muscle plasma membrane that forms the synaptic trough is pleated to form postjunctional folds.
