During a conversation with a friend, you tell him that you recently learned in your biology class that acetylcholine release by
a motor neuron triggers an action potential in a muscle fiber, causing it to contract. Your friend tells you that he heard that Botox injections into facial muscles underlying the skin inhibit contraction of the muscles that cause a particular type of facial wrinkle. He asks how Botox does this. What will you tell him
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.
yes because the earth is always rotating you dont realize it but it is always going round the sun and we learn that in school but you dont really see them moving so probably not is the answer
