Acetylcholine

Acetylcholine (ACh) was the first neurotransmitter ever to be discovered and is essential for communication between nerves and muscles. It is the chemical that motor neurons release to activate muscles, making it fundamental for every movement, from blinking to breathing. Within the autonomic nervous system, acetylcholine is the chief neurotransmitter of the parasympathetic branch, which slows the heart rate, contracts smooth muscles, and increases bodily secretions. In the brain, it plays a vital role in arousal, attention, learning, and memory. A significant shortage of acetylcholine is a key feature of Alzheimer's disease.
