: Heavy metals like lead , mercury , and arsenic , as well as synthetic pesticides, are significant environmental neurotoxins.
Neurotoxins operate by attacking the cellular and molecular machinery of the nervous system: neurotoxin
Neurotoxins are found in a variety of natural and synthetic forms: : Heavy metals like lead , mercury ,
: Some effects are fleeting, such as the temporary coordination loss from alcohol consumption, while others—like cognitive damage from lead or mercury exposure—can be irreversible. Major Types and Sources : Many neurotoxins, such as those in snake
: Includes bacterial toxins (botulism, tetanus), animal venoms (snakes, scorpions), and certain plant compounds.
: Many neurotoxins, such as those in snake venom, bind to neurotransmitter receptors (like nAChR), preventing the chemical messengers from delivering signals between cells.
A is a poisonous substance that specifically targets, disrupts, or destroys nerve tissue. This extensive class of chemical insults can interfere with the way neurons communicate, leading to immediate or long-lasting functional impairment in the nervous system. Mechanisms and Physiological Effects
