adrenergic
Epinephrine-activated nerve pathways
Adrenergic describes nerve fibers or receptors that respond to adrenaline (epinephrine) and related compounds.
The term appears in pharmacology and physiology: adrenergic receptors, adrenergic drugs.
Beta-blockers and similar medications work by blocking adrenergic activity.
The opposite is cholinergic, which relates to acetylcholine.
