What class of chemicals do nerve agents belong to?

• A. Oxidizing agents
• B. Carcinogens
• C. Cholinesterase inhibitors
• D. Heavy metals

Answer: (C)

Nerve agents are classified as cholinesterase inhibitors due to their mechanism of action within the nervous system. These agents work by inhibiting the enzyme acetylcholinesterase, which is responsible for breaking down the neurotransmitter acetylcholine in the synaptic cleft. When acetylcholine is not broken down, it accumulates, leading to overstimulation of the nervous system, resulting in a range of physiological effects including muscle paralysis, respiratory failure, and potentially death. Understanding that nerve agents fall under this category is crucial for recognizing the dangers they pose and the methods needed to counteract their effects, such as the administration of antidotes like atropine or pralidoxime, which function by restoring the normal activity of the nervous system. This classification is vital for emergency responders and military personnel in comprehending the risks and preparing appropriate responses to nerve agent exposure.
