Thân thiện

A neuron releases cholinergic neurotransmitters at a synapse.

Definition

1. Adjective:
   • Releasing or activated by acetylcholine or a related compound: Describing nerve cells, fibers, or drugs that function by releasing or responding to the neurotransmitter acetylcholine.

Usage

• The term is primarily used in medical, biological, and pharmacological contexts to describe the components of the nervous system or substances that involve acetylcholine.
• It is often contrasted with "adrenergic" (involving adrenaline/noradrenaline).

Examples

• Adjective:
  • The parasympathetic nervous system is primarily cholinergic.
  • This medication has a cholinergic effect, which can help improve muscle strength.
  • Researchers studied the cholinergic neurons in the brain.

Advanced Usage

• "Cholinergic crisis": A medical condition caused by excessive stimulation at cholinergic nerve junctions, often due to an overdose of certain medications.
  • The patient's symptoms were consistent with a cholinergic crisis.
• "Cholinergic receptor": A protein structure on a cell surface that responds to acetylcholine.
  • Nicotinic and muscarinic receptors are two main types of cholinergic receptors.

Variants and Related Words

• Cholinesterase (n): An enzyme that breaks down acetylcholine, terminating its signal.
  • Some nerve agents work by inhibiting cholinesterase.
• Anticholinergic (adj): Having the opposite effect of cholinergic agents; blocking acetylcholine.
  • The drug's anticholinergic side effects include dry mouth and blurred vision.

Synonyms

• Acetylcholine-related: Pertaining to acetylcholine.
• Parasympathomimetic: Producing effects similar to stimulation of the parasympathetic nervous system (often a subset of cholinergic effects).

Antonyms

• Adrenergic: Activated by or related to adrenaline (epinephrine) or noradrenaline.
• Noradrenergic: Releasing or activated by noradrenaline.

Related Phrases

• Cholinergic neurotransmission: The process of signal transmission using acetylcholine.
  • The lecture focused on the mechanisms of cholinergic neurotransmission.
• Cholinergic system: The network of neurons in the body that use acetylcholine.
  • Degeneration of the cholinergic system is associated with Alzheimer's disease.
