Latrotoxin,produced by the poisonous black widow spider,increases the release of acetylcholine.How do muscle cells respond?

Question

Quizplus · Accepted Answer

When excess acetylcholine is present, muscle cells will experience increased and sustained contraction, known as tetanus. If the tetanus is complete, the muscles will become locked and paralyzed. Fused tetanus occurs when the frequency of contractions is so high that the individual twitches fuse together into a sustained contraction. This is the most likely outcome if latrotoxin increases acetylcholine release.
