Question

Botulism affects

• A. Digestive system
• B. Blood vascular system
• C. Nervous system
• D. Respiratory system

Answer 1

The correct option is C Nervous system

Botulism is caused by Clostridium botulinum. The organism releases a neurotoxin which acts on the nerves. The neurotoxin enters the nerve cells and interferes with the release of acetylcholine so the nerve cannot stimulate the muscle to contract. The toxin paralyzes the nerves so that the muscles cannot contract.

So, the correct answer is 'Nervous system'
