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 a neurotransmitterâa chemical messenger that helps carry signals across a nerve synapse. It was the first neurotransmitter to be discovered, and has been heavily studied. It is also the most abundant neurotransmitter and is present in both the central nervous system and peripheral nervous system.cetylcholine works together with the neurotransmitter dopamine to enable smooth movements. When there is an imbalance between acetylcholine and dopamine, movements can be shaky and uneven, a hallmark of Parkinsonâs disease. References: 1  Alzheimerâs disease medication fact sheet.
