Neurotoxin

A neurotoxin is a type of poison that specifically targets and disrupts the function of nerve cells (neurons) in the body. These substances can interfere with how nerves communicate, leading to symptoms like paralysis, muscle weakness, or even death. Neurotoxins can come from various sources, including certain animals (like pufferfish and certain snakes), bacteria (like botulinum), and some plants. Their effects can vary widely, depending on the type of neurotoxin and the dose, making them potentially very dangerous if ingested or absorbed into the body.
