Deadliest substances known to humans are:

• A. Hemotoxins
• B. Enterotoxins
• C. Neurotoxins
• D. Myotoxins

Answer: (C)

Disrupting nerve signaling leads to rapid, life-threatening failure of critical functions, especially breathing. Neurotoxins act on the nervous system, stopping nerves from telling the muscles what to do. This can produce swift, profound paralysis, including paralysis of the respiratory muscles, which can cause death with only a tiny amount of toxin. Botulinum toxin is a prime example of a neurotoxin with extreme potency, so small doses can be fatal by respiratory failure. Because of this extreme potency and the speed at which they can shut down vital processes, neurotoxins are among the deadliest substances known to humans. Hemotoxins, enterotoxins, and myotoxins cause serious harm in their own ways, but their lethal effects are typically not as rapid or as overwhelmingly fatal at such low doses as those of neurotoxins.
