Answer:

Explanation:

Botulinum toxin (Botox) is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species

Botulinum toxin commonly acts by binding to high-affinity recognition sites on the cholinergic nerve terminals and decreasing the release of acetylcholine, causing a neuromuscular blocking effect. Through this mechanism, muscle movement is inhibited in the area it is injected to.
