releasing or activated by acetylcholine or a related compound
Acetylcholine is a chemical produced at many nerve endings in the body, and receptors which bind acetylcholine are called cholinergic receptors. Cholinergic nerves regulate heart rate, blood pressure, digestive processes, bowel and bladder function, memory, alertness, eye pressure and muscle function. Drugs that block these nerves (see anticholinergic) can alter these bodily functions.
Description of a nerve ending or synapse where acetylcholine is released as the primary transmitter
Fibers in the parasympathetic nervous system that release a chemical called acetylcholine.
resembling acetylcholine, especially in physiological action. Cholinergic symptoms include nausea, vomiting, headache and sweating.
neurotransmitter - neurotransmitter built from a chemical called choline.
the parts of the nervous system that use acetylcholine as a neurotransmitter.
pertaining to acetylcholine; the cholinergic system includes the neurons that contain acetylcholine and the neurons and proteins that are stimulated or activated by acetylcholine.
resembling acetylcholine in action, a cholinergic drug for example. Cholinergic nerve fibers liberate or are activated by the neurotransmitter, acetylcholine.
Those parts of the nervous system, both peripheral and in the brain, using acetylcholine as a neurotransmitter. Acetylcholine released at the synapse (junction) between a motor nerve and a muscle fiber causes the muscle fiber to contract. Acerylcholine is am important brain neurotransmitter, too, being involved in memory, long-term planning, control of mental focus, sexual activity, and other functions. It is made in the body from choline in reactions requiring the availability of adequate vitamin B-5 (as part of hte acetyl co-enzyme A).
The term that describes receptors and neurotransmitters of the parasympathetic nervous system.
Relating to nerve cells or fibers that employ acetylcholine as their neurotransmitter.
A synapse is cholinergic if it uses acetylcholine as its neurotransmitter.
