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.

Summary. â¢ Each skeletal muscle cell is individually stimulated by a motor neuron. â¢ The neuromuscular junction is the place where the terminal portion of a motor neuron axon meets a muscle cell membrane, separated by a synaptic cleft.â¢ An action potential arriving at the axon terminal brings about the release of acetylcholine, which leads to depolarization of the motor end plate.age 1. Introduction. â¢ Motor neurons stimulate muscle cells to contract at the neuromuscular junction. Page 2. Goals. â¢ To examine the structure of a neuromuscular junction. â¢ To understand the sequence of events occurring at the neuromuscular junction following a stimulus. Page 3.
