A neurotransmitter essential for muscle activation, memory formation, attention, and the parasympathetic nervous system.
From 'acetyl' (chemical group from acetic acid) + 'choline' (from Greek 'chole,' bile). First neurotransmitter discovered, by Otto Loewi in 1921.
Acetylcholine was the first neurotransmitter ever discovered — it's crucial for memory, attention, and telling your muscles to move!
