  2. Norepinephrine - Wikipedia

    en.wikipedia.org/wiki/Norepinephrine

    The general function of norepinephrine is to mobilize the brain and body for action. Norepinephrine release is lowest during sleep, rises during wakefulness, and reaches much higher levels during situations of stress or danger, in the so-called fight-or-flight response. In the brain, norepinephrine increases arousal and alertness, promotes ...

  3. Counterregulatory hormone - Wikipedia

    en.wikipedia.org/wiki/Counterregulatory_hormone

    The action of insulin is counterregulated by glucagon, epinephrine (), norepinephrine (noradrenaline), cortisol, and growth hormone.These counterregulatory hormones—the term is usually used in the plural—raise the level of glucose in the blood by promoting glycogenolysis, gluconeogenesis, ketogenesis, and other catabolic processes.

  4. Peripheral nervous system - Wikipedia

    en.wikipedia.org/wiki/Peripheral_nervous_system

    Neurotransmitters such as norepinephrine, and epinephrine are released, [8] which increases heart rate and blood flow in certain areas like muscle, while simultaneously decreasing activities of non-critical functions for survival, like digestion. [9]

  5. Catecholamine - Wikipedia

    en.wikipedia.org/wiki/Catecholamine

    Catecholamines are produced mainly by the chromaffin cells of the adrenal medulla and the postganglionic fibers of the sympathetic nervous system. Dopamine, which acts as a neurotransmitter in the central nervous system, is largely produced in neuronal cell bodies in two areas of the brainstem: the ventral tegmental area and the substantia nigra, the latter of which contains neuromelanin ...

  7. Attention deficit hyperactivity disorder - Wikipedia

    en.wikipedia.org/wiki/Attention_deficit...

    [187] [15] The dopamine pathways and norepinephrine pathways which project to the prefrontal cortex and striatum are directly responsible for modulating executive function (cognitive control of behaviour), motivation, reward perception, and motor function; [186] [15] these pathways are known to play a central role in the pathophysiology of ADHD.

  8. L-DOPA - Wikipedia

    en.wikipedia.org/wiki/L-DOPA

    l-DOPA is the precursor to the neurotransmitters dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline), which are collectively known as catecholamines. Furthermore, l-DOPA itself mediates neurotrophic factor release by the brain and CNS.
