What is Botox?
Botox is a trade name for botulinum toxin A. In this way, Botox is related to botulism. Botulism is a form of food poisoning. Botulinum toxin A is one of the neurotoxins (a neurotoxin is a toxin that acts specifically on nervous tissue) produced by Clostridium botulinum.
The most serious symptom of botulism is paralysis, which in some cases has proven to be fatal. 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. A series of proteins are essential for the release of acetylcholine. Certain botulinum toxins attack these proteins. Basically, the botulinum toxins block the signals that would normally tell your muscles to contract. Say, for example, it attacks the muscles in your chest — this could have a profound impact on your breathing. When people die from botulism, this is often the cause — the respiratory muscles are paralyzed so its impossible to breathe.
