The botulinum toxins (there are seven -- types are A through G) - TopicsExpress



          

The botulinum toxins (there are seven -- types are A through G) attach themselves to nerve endings. Once this happens, acetylcholine, the neurotransmitter responsible for triggering muscle contractions, cannot be released.
