The most common neurotransmitter is called acetylcholine.
Little did I suspect then what I was able to show many years later - namely, that relaxation of arteries by acetylcholine is strictly endothelium-dependent, and that my method of preparing the strips inadvertently resulted in the mechanical removal of all the endothelial cells.
Sir Bernard Katz 'discoveries concerning the mechanism for the release of the transmitter acetylcholine from the nerve terminals at the nerve-muscle junction, under the influence of the nerve impulses, are fundamental not only for the understanding of the so-called cholinergic transmission, but are also of primary importance for our knowledge about the synaptic transmission between the nerve cells in the central nervous system.
In a sympathetic ganglion, the synaptic junctions, at which the acetylcholine is released by the incident preganglionic impulses, form a large part of the small amount of tissue perfused.
Nicotinic receptors use a neurotransmitter called acetylcholine, too.
Eat an apple or two: Apples stimulate production of the neurotransmitter acetylcholine, which is what the Alzheimer's drug Aricept also does, say University of Massachusetts researchers.
Reduces the natural relaxation and anti-inflammatory calming, memory-enhancing neurotransmitter called acetylcholine.
Rosemary contains chemicals called acetylcholinestrase inhibitors, which prevent the breakdown of a chemical produced by the brain, called acetylcholine.
We stay awake because the hypothalamus secretes a chemical called acetylcholine that dams up the onslaught of GABA.
Eggs are rich in choline, a B vitamin that is a key component in the brain transmitter acetylcholine, which is crucial for memory.
