Question

If a poison is ingested that prevents the release of acetylcholine, which one of the following would occur at a myoneural junction?

Answer 1

Answer;

The sodium and potassium gates on the motor end plate will not open

Explanation;

• Poisons are substances that are harmful or toxic to living organisms. They include biological compounds and also artificial compounds.

• Upon exposure, poisons may disrupts metabolic process or destroy tissues through chemical reactions with cells.

• Poisons such as Botulinum toxin, when ingested cause oxygen deprivation in the body. This poison prevents the release of acetylcholine by neurons at the neuromuscular junction since the potassium and sodium ions gates do not open. Without this neurotransmitter, the respiratory muscles cannot contract.

Answer 2

Had to look for the options and here is my answer.
Given the situation that a poison is consumed and this prevented the acetylcholine release, the one that would most likely occur at a myoneural junction is that "sodium and potassium gates on the motor end plate will not open". Hope this helps.
