(ad-rĕ-ner'jik),
1. Relating to nerve cells or fibers of the autonomic nervous system that use norepinephrine as their neurotransmitter. Compare: cholinergic.

adrenergic

(ăd′rə-nûr′jĭk)
adj.
1. Activated by or capable of releasing epinephrine or a similar substance, especially in the sympathetic nervous system: adrenergic receptors.
2. Having physiological effects similar to those of epinephrine: an adrenergic amine.

Adrenergic

adjective Referring to
(1) Neural activation by catecholamines—e.g., adrenaline/epinephrine, noradrenaline/norepinephrine, dopamine.
(2) Sympathetic nerve fibres that liberate catecholamines into a synapse.
noun Any agent with adrenergic-agonist activity.

adrenergic

Having effects similar to those of ADRENALINE. Drugs with adrenaline-like action are called adrenergic. A nerve which releases noradrenaline (a substance closely related to adrenaline) at its endings to pass on its impulses to other nerves, or to muscle fibres, is described as an adrenergic nerve.

adrenergic

(of nerve endings) secreting ADRENALINE and NORADRENALINE on the arrival of a NERVE IMPULSE. These substances then stimulate the effector nerve fibres in the SYMPATHETIC NERVOUS SYSTEM of many vertebrates in much the same way as ACETYLCHOLINE acts as a transmitter substance in CHOLINERGIC nerve fibres.

Adrenergic

Activated by adrenalin (norepinephrine), loosely applied to the sympathetic nervous system responses.

adrenergic 

1. Relating to a neuron that is activated or capable of releasing adrenaline (epinephrine).
2. Having an effect similar to adrenaline (epinephrine).
3. Relating to drugs that mimic the effects of the sympathetic nervous system (sympathomimetic drugs).
