  2. Adrenergic storm - Wikipedia

    en.wikipedia.org/wiki/Adrenergic_storm

    An adrenergic storm is a sudden and dramatic increase in serum levels of the catecholamines adrenaline and noradrenaline (also known as epinephrine and norepinephrine respectively), with a less significant increase in dopamine transmission.

  3. Adrenaline - Wikipedia

    en.wikipedia.org/wiki/Adrenaline

    For example, high levels of adrenaline cause smooth muscle relaxation in the airways but causes contraction of the smooth muscle that lines most arterioles. Adrenaline is a nonselective agonist of all adrenergic receptors, including the major subtypes α 1, α 2, β 1, β 2, and β 3. [73]

  4. Adrenergic receptor - Wikipedia

    en.wikipedia.org/wiki/Adrenergic_receptor

    Although α receptors are less sensitive to epinephrine, when activated at pharmacologic doses, they override the vasodilation mediated by β-adrenoreceptors because there are more peripheral α 1 receptors than β-adrenoreceptors. The result is that high levels of circulating epinephrine cause vasoconstriction.

  5. Sympathoadrenal system - Wikipedia

    en.wikipedia.org/wiki/Sympathoadrenal_system

    The mechanism lies in epinephrine being secreted by the adrenal medulla and activating glycogenolysis (the breakdown of glycogen into glucose, or promoting gluconeogenesis (glucose formation). While epinephrine has a greater effect in glucose production, norepinephrine can also increase glucose levels but at high concentrations.

    The approval was based on studies in 175 healthy adults measuring concentrations of epinephrine in the blood, which showed comparable levels for Neffy and injected epinephrine, as well as similar ...

  7. Stress (biology) - Wikipedia

    en.wikipedia.org/wiki/Stress_(biology)

    The high glucose, fat and amino acid levels in blood prove useful for anabolic reactions, restoration of homeostasis and regeneration of cells. Exhaustion is the alternative third stage in the GAS model. At this point, all of the body's resources are eventually depleted and the body is unable to maintain normal function.

  8. Lipolysis - Wikipedia

    en.wikipedia.org/wiki/Lipolysis

    Induced by high epinephrine and low insulin levels in the blood, epinephrine binds to beta-adrenergic receptors on the cell membrane of the adipocyte, which causes cAMP to be generated inside the cell. The cAMP activates protein kinases, which phosphorylate and thus activate hormone-sensitive lipases in the adipocyte.

  9. Catecholamine - Wikipedia

    en.wikipedia.org/wiki/Catecholamine

    High catecholamine levels in blood are associated with stress, which can be induced from psychological reactions or environmental stressors such as elevated sound levels, intense light, or low blood sugar levels. [10] Extremely high levels of catecholamines (also known as catecholamine toxicity) can occur in central nervous system trauma due to ...
