a toxic substance that inhibits the cholinesterase enzyme and therefore elevates the acetylcholine level in the body. Symptoms are pinpoint pupils, difficulty focusing, headache, and secretion from the skin and mucous membranes. Nausea, vomiting, and loss of bladder and bowel control lead to severe dehydration. These lead to general muscular fasciculation followed by violent convulsions, coma, respiratory arrest, and death.
A chemical weapon that interferes with the transmission of the body's nerve impulses.
a toxic gas that is inhaled or absorbed through the skin and has harmful effects on the nervous and respiratory system
an 'Acetylcholinesterase Inhibitor'
A substance that interferes with the central nervous system. Exposure is primarily through contact with the liquid (skin and eyes) and secondarily through inhalation of the vapor. Three distinct symptoms associated with nerve agents are: pinpoint pupils, an extreme headache, and severe tightness in the chest. Examples of nerve agents are: sarin, Soman, tabun, and VX agent.
the nerve agents (GA, GB, and VX) are lethal colorless, odorless, and tasteless agents that can be fatal upon skin contact or when inhaled. These agents attack the central nervous system by inhibiting the production of acetylcholinesterase, which is essential for proper operation of the nervous system.
Nerve agents (also known as nerve gases, though these chemicals are liquid at room temperature) are a class of phosphorus-containing organic chemicals (organophosphates) that disrupt the mechanism by which nerves transfer messages to organs. The disruption is caused by blocking acetylcholinesterase, an enzyme that normally relaxes the activity of acetylcholine, a neurotransmitter. As chemical weapons, they are classified as weapons of mass destruction by the United Nations according to UN Resolution 687, and their production and stockpiling was outlawed by the Chemical Weapons Convention of 1993; the Chemical Weapons Convention officially took effect on April 291997.
