Like some of the chemical weapons, biological weapons may also be useful as area denial weapons. These agents may be lethal or non-lethal, and may be targeted against a single individual, a group of people, or even an entire population.
Acetylcholine is a chemical messenger, a neurotransmitter, released by nerve cells in many parts of the peripheral nervous system. It controls the contraction of all skeletal or voluntary muscles, for instance. It also affects the contraction of smooth and cardiac muscle.
Acetylcholine is found at the synapses between neurons and muscle cells. It serves to activate the muscle to contract. If acetylcholine receptors sites on the muscle cell are blocked in someway, then the acetylcholine cannot get on the site and the muscles will be incapable of contracting-paralyzed that is.here are two main classes of acetylcholine receptors(acetylcholine receptor is an integral membrane protein that responds to the binding of acetylcholine neurotransmitter), nicotinic acetylcholine receptors and muscarinic acetylcholine receptors.
