Acetylcholine
Tuesday, June 14, 2011 8:06:20 AM
A chemical messenger called acetylcholine, abbreviated ACh, is responsible for voluntary muscle movements through the motor neurons. Perhaps, there is a confusion as to what a chemical messenger is; ...the physiological chemical in the body that carries information to parts of the human system. This is too general. Hormones are chemical messengers as well. Does this definition make acetylcholine a hormone? No. Acetylcholine is actually a neurotransmitter. Wayne Weiten (2010) describes a neurotransmitter as a chemical that transmits information from one neuron to another. This means neurotransmitters such as acetylcholine are found in the nervous tissue, not in the blood system like hormones are.
The role of acetylcholine
Every move you make, such as typing, walking, talking, breathing, fucking and so forth, depends on ACh released to your muscles by motor neurons. This neurotransmitter also shows to contribute to attention, arousal, and memory (Weiten. W, 2010:85).
Shortage of acetylcholine
Memory loss in Alzheimer's is associated with the shortage of acetylcholine in other parts of the brain. This does not mean that ACh shortage is a direct cause of Alzeimer's.
