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 an organic chemical that functions in the brain and body of many types of animals as a neurotransmitter âa chemical released by nerve cells to send signals to other cells. Its name derives from its chemical structure: it is an ester of acetic acid and choline.4) Acetylcholine binds to postsynaptic receptors. (5) This binding causes ion channels to open and allows sodium ions to flow into the muscle cell. (6) The flow of sodium ions across the membrane into the muscle cell generates an action potential which induces muscle contraction.
