Which type of poison is classified as a neurotoxin?

Neurotoxins are substances that specifically target nerve cells, disrupting the normal functioning of the nervous system. This class of poisons can interfere with neurotransmission, damage neuronal structures, or disrupt neuronal function by various mechanisms.

For instance, certain neurotoxins can block the action of neurotransmitters, which inhibits the communication between nerve cells, leading to symptoms such as paralysis or seizures. Examples of neurotoxins include compounds found in certain snake venoms, some types of shellfish, and various chemical substances designed for pest control.

While pesticides can contain neurotoxic agents, not all pesticides are classified as neurotoxins. Similarly, metals like lead or mercury have their own toxic effects but do not exclusively target the nervous system in the same manner as neurotoxins do. Cardiotoxins primarily affect the heart and the cardiovascular system, rather than the nervous system. Therefore, the classification of a substance as a neurotoxin hinges on its specific action on nerve tissues, making this category unique and precise in its effects.
