Which body system is primarily affected by organophosphates and carbamates?

• A. Nervous system
• B. Digestive system
• C. Endocrine system
• D. Lymphatic system

Answer: (A)

Organophosphates and carbamates primarily disrupt nerve signaling. They inhibit acetylcholinesterase, the enzyme that breaks down acetylcholine at nerve endings. When acetylcholine accumulates, it overstimulates cholinergic receptors throughout the body, especially at the neuromuscular junction and along autonomic nerves. That direct impact on how nerves communicate is why the nervous system is the best answer. You may see secondary effects in other areas (like digestion or glands) because of the widespread cholinergic activity, but the hallmark and primary target are the nervous system.
