What type of toxin primarily affects the nervous system?

Explanation:
Neurotoxins are toxins that primarily disrupt nervous system function by interfering with nerve signaling—whether by blocking ion channels, preventing neurotransmitter release, or damaging neurons. This direct impact on how nerves communicate leads to symptoms like weakness, numbness, paralysis, or seizures depending on exposure. That’s why this type of toxin best fits the question about the nervous system. In contrast, hepatotoxins damage the liver, cardiotoxins affect the heart, and nephrotoxins damage the kidneys. Some toxins can affect more than one organ, but the defining feature here is the nervous system focus.
