noun
definition
A neurotransmitter in humans and other animals. It is an ester of acetic acid and choline with chemical formula CH3COOCH2CH2N+(CH3)3.
Examples of acetylcholine in a Sentence
The choline found in lecithin is used to make acetylcholine in the body.
The first medicines assessed for Alzheimer's treatment work in this way and are called acetylcholine esterase inhibitors.
There was no significant difference between groups in MMH or in the response to acetylcholine iontophoresis.
These may come from new approaches such as the role of sigma, NMDA and acetylcholine receptors.
Papers describing the coronary vasodilator effects of acetylcholine in humans have appeared in prestigious journals from 1987 until the present.
Specifically, acetylcholine, a chemical in the body that transmits nerve signals, is released from nerve endings and stimulates secretion of sweat.
Anticholinergic drug-Drugs that block the action of the neurotransmitter acetylcholine.
Also, botulinum toxin is a neurotoxin that blocks the ability of motor nerves to release acetylcholine, the neurotransmitter that relays nerve signals to muscles.
Drug A attaches to the acetylcholine receptors on the smooth muscle without stimulating them and prevents acetylcholine from gaining access to them.
Also, choline is used to produce the important neurotransmitter acetylcholine.
They always use the neurotransmitter acetylcholine, and are always excitatory.
However, Reminyl also appears to act on the nicotinic neuronal receptors in the body, making them release more acetylcholine.
When enough acetylcholine attaches itself to the outer surface of a muscle cell, the muscle cell becomes ' excited enough ' to contract.
Many types of smooth muscle also contain gap junctions and muscarinic acetylcholine receptors, but here acetylcholine normally leads to contraction.
Alzheimer's disease is caused by the destruction of certain brain cells leading to the loss of the neurotransmitter acetylcholine.

Choline is transformed into the brain neurotransmitter acetylcholine, which is vital to the efficient transmission of brain signals.
Terminal nerve fibers release acetylcholine into the neuromuscular junction, which then binds to acetylcholine receptors on muscle cells.
These proteins control the release of acetylcholine, a neurotransmitter that stimulates muscle cells.
With acetylcholine release blocked, nerves are not able to stimulate muscles.
Anticholinergics, including trihexyphenidyl (Artane) and benztropine (Benztrop MES, Cogentin), block acetylcholine receptors in the brain.
Acetylcholine receptors are integral proteins that respond to the neurotransmitter acetylcholine by opening a pathway in the membrane for ion diffusion across the cell membrane.
