Having to de with adrenaline (epinephrine) and/or noradrenaline (norepinephrine).
Referring to neural activation by catecholamines such as epinephrine (adrenaline) and norepinephrine (noradrenaline) as well as drugs with adrenaline-like action that are capable of binding adrenergic receptors. Contrast with cholinergic.
A substance that binds to adrenergic neuroreceptors and produces an effect similar to the normal impulses (caused by adrenaline, noradrenaline) of the sympathetic nervous system; antagonists are sympatholytics.
Pertaining to nerves, receptors, or actions that involve the release of epinephrine or norepinephrine. Most postganglionic sympathetic nerve fibers are adrenergic.
Referring to a neurone or receptor which is stimulated by adrenaline.
Refers to synapses or physiologic responses involving epinephrine and norepinephrine.
Indicating a relationship to either epinephrine or norepinephrine, their release, or their actions, esp. in association with the sympathetic nervous system; also called sympathomimetic.
Describing nerve fibers that release norepinephrine as a neurotransmitter.
Relating to nerve fibers that release norepinephrine or epinephrine at synapses.
Any one of a group of therapeutic agents that mimic or stimulate the sympathetic nervous system.
These specialized nerve cells, commonly referred to as catecholaminergic neurons, employ catecholamines as neurotransmitters at synaptic junctions. Catecholamines, including substances like dopamine, norepinephrine, and epinephrine, serve as crucial chemical messengers in facilitating communication between neurons.
A compound that connects to adrenergic neuroreceptors, eliciting a reaction akin to the natural impulses (triggered by adrenaline, noradrenaline) of the sympathetic nervous system; substances that counteract this effect are known as sympatholytics.
