They are all extremely dangerous and they can enter the body through the air or on contact with the skin. They can be released using bombs, missiles, spray tanks, rockets and land mines. Nerve agents are more dense than air so they are especially dangerous to people in low areas. Method of Action Acetylcholine is a common neurotransmitter found in the central and peripheral nervous system. Acetylcholine is also used in the autonomic nervous system .
Nerve agents bind to part of the AChE molecule.
This makes the AChE inactive and blocks the action of AChE . Acetylcholinesterase ACh is released at the axon terminal. ACh crosses the synaptic cleft. ACh binds with a receptor on the post-synaptic membrane. ACh crosses the synaptic cleft.
