What do neurotoxins like DDT and chlordane primarily damage?

Neurotoxins such as DDT (dichlorodiphenyltrichloroethane) and chlordane primarily target the nervous system. These compounds disrupt normal neuronal function, which can lead to a range of neurological issues. They work by interfering with neurotransmission, causing overstimulation of nerves, which can ultimately affect motor control, cognition, and other essential bodily functions mediated by the nervous system.

The nervous system is particularly sensitive to the effects of neurotoxins because it relies on precise chemical signaling between neurons. The impairment of these signaling pathways can result in symptoms like tremors, seizures, and even long-term cognitive deficits. Understanding the specific impact of neurotoxins is crucial for evaluating risks associated with exposure and developing preventive measures in environments where these chemicals are present.

The other options reflect systems that may not be directly affected by neurotoxins in the same manner. While exposure to certain chemicals can lead to issues in those systems, DDT and chlordane are notorious for their specific targeting of neurological pathways.
