Nerve poisons, or nerve gases are organic chemicals that interfere with the mechanism by which nerves transfer messages to organs. The interference is as a result of the blocking of acetylcholinesterase, and enzyme that catalyzes the breakdown of acetycholine, a neurotransmitter. Therefore, a poison that blocks acetylcholine receptors on dendrites may reduce or decrease the binding of acetycholine to its receptors on the postsynaptic membrane.
