Definition

1. Adjective:

   • Relating to or denoting nerve cells or fibers that release or are affected by epinephrine (adrenaline) or similar substances: This describes physiological processes, receptors, or agents that involve adrenaline-like neurotransmitters.
   • Mimicking the action of epinephrine: Used to describe drugs or effects that stimulate the sympathetic nervous system.

2. Noun:

   • A drug or other agent that causes stimulation of the sympathetic nervous system: A substance that produces effects similar to those of epinephrine (adrenaline).

Usage Examples

• Adjective:

  • The adrenergic receptors in the heart respond to stress hormones.
  • An adrenergic response, such as increased heart rate, is part of the "fight or flight" reaction.

• Noun:

  • The doctor prescribed an adrenergic to treat the severe asthma attack.
  • Some nasal decongestants are adrenergics that constrict blood vessels.

Advanced Usage

• "Adrenergic neurotransmission": The process by which signals are transmitted in the nervous system using norepinephrine or epinephrine as neurotransmitters.

  • The study focused on disorders of adrenergic neurotransmission.

• "Adrenergic agonist/antagonist": An agonist is a drug that stimulates adrenergic receptors; an antagonist is a drug that blocks them.

  • Beta-blockers are adrenergic antagonists used to manage high blood pressure.

Variants and Related Words

• Adrenaline (Epinephrine) (n): The primary hormone and neurotransmitter involved in the adrenergic response.

  • Adrenaline is released during times of excitement or fear.

• Noradrenergic (adj): Specifically relating to or denoting nerve cells or fibers that release or are affected by norepinephrine (noradrenaline).

  • Noradrenergic neurons are involved in attention and arousal.

Synonyms

• Sympathomimetic (adj/n): Having an effect resembling that of stimulation of the sympathetic nervous system.
• Catecholaminergic (adj): Relating to or denoting nerve cells or fibers that use catecholamines (like epinephrine or norepinephrine) as neurotransmitters. (This is a broader, more technical term.)

Related Phrases and Compounds

• Adrenergic receptor: A type of receptor on cell surfaces that binds adrenaline or noradrenaline.

  • Beta-2 adrenergic receptors in the lungs help relax airway muscles.

• Adrenergic storm: A sudden, severe overactivity of the sympathetic nervous system.
