Acetylcholine (ACh): What It Is, Function & Deficiency

Acetylcholine (ACh) is an important neurotransmitter that plays a role in brain functions, such as memory, and body functions, such as muscle contractions to move your muscles. Low levels of acetylcholine are associated with memory issues and muscle disorders. Cholinesterase inhibitors are used to treat Alzheimer's disease and myasthenia gravis.

Synthesis, Storage and Release of Acetylcholine

A second transport system concentrates acetylcholine in the synaptic vesicle. ACh is transported into storage vesicles following its synthesis by ChAT in the nerve ending [].The vesicular ACh transporter has been cloned and expressed.Its sequence places it in the 12-membrane-spanning family characteristic of other biogenic amine transporters found in adrenergic nerve endings …

Acetylcholine

Acetylcholine (ACh) is a neurotransmitter used by somatic efferent neurons, preganglionic sympathetic neurons, and the parasympathetic nervous system. Acetylcholine was the first neurotransmitter ever identified, and is well understood since it is released at neuromuscular junctions—locations that are easier to study than the deeply buried CNS synapses.

Acetylcholine: Function, Associated Conditions, and More

You can lower levels of acetylcholine with prescription anticholinergic drugs, but the appropriate drug depends on the body system. For example, acetylcholine imbalance associated with brain conditions may be treated differently than that of asthmatic conditions. Your doctor can help determine what, if any, medication is necessary.

Acetylcholine and cholinergic receptors

Acetylcholine as a neurotransmitter. By 1967, acetylcholine (ACh) was firmly accepted as a major neurotransmitter in the peripheral nervous system, including somatic motor nerves and parts of the autonomic nervous system (see, e.g. Goodman and Gilmam, 1965; Krnjevic, 1974).Enzymes for its synthesis ( 'choline acetylase' = choline acetyltransferase) and …
