Organic results of poisoning from exposure to organic pesticide poison which causes inhibition of the enzyme acetylcholine, leading to the accumulation of acetylcholine in the body (cholinergic poisoning). Organophosphates that prevent inhibition activity أستيلكولينستراز.أستيلكولينستراز critical to the functions of the nerves, so the blockage of this enzyme causes the accumulation of acetylcholine, leading to overgrowth of muscle. This causes disruption across cholinergic synapses. Acetylcholine also known as acetylcholinesterase, an enzyme degrades hydrolyst activity of the enzyme, choline neurotransmitter acetylcholine product's acetate group. Where its activity serves to terminate synaptic
