  2. Adrenaline - Wikipedia

    en.wikipedia.org/wiki/Adrenaline

    Adrenaline does not readily cross the blood-brain barrier, so its effects on memory consolidation are at least partly initiated by β adrenoceptors in the periphery. Studies have found that sotalol , a β adrenoceptor antagonist that also does not readily enter the brain, blocks the enhancing effects of peripherally administered adrenaline on ...

  3. Alpha-1 adrenergic receptor - Wikipedia

    en.wikipedia.org/wiki/Alpha-1_adrenergic_receptor

    Blood vessels with α 1-adrenergic receptors are present in the skin, the sphincters [4] of gastrointestinal system, kidney (renal artery) [5] and brain. [6] During the fight-or-flight response vasoconstriction results in decreased blood flow to these organs. This accounts for the pale appearance of the skin of an individual when frightened.

    The second hypothesis found support from 1906 to 1913, when Henry Hallett Dale explored the effects of adrenaline (which he called adrenine at the time), injected into animals, on blood pressure. Usually, adrenaline would increase the blood pressure of these animals. Although, if the animal had been exposed to ergotoxine, the blood pressure ...

    Transient hypertension (increase in blood pressure), followed by a sustained hypotension (decrease in blood pressure) [5] Vasoconstriction of certain arteries [9] Vasoconstriction of arteries to heart (coronary artery); [10] however, the extent of this effect may be limited and may be negated by the vasodilatory effect from β 2 receptors [11]

  6. Norepinephrine - Wikipedia

    en.wikipedia.org/wiki/Norepinephrine

    The consequence is a massive increase in the amount of norepinephrine and epinephrine released into the bloodstream. The most obvious symptoms are those of sympathetic hyperactivation, including particularly a rise in blood pressure that can reach fatal levels. The most effective treatment is surgical removal of the tumor.

  8. Sympathetic nervous system - Wikipedia

    en.wikipedia.org/wiki/Sympathetic_nervous_system

    The synthesis and release of epinephrine as opposed to norepinephrine is another distinguishing feature of chromaffin cells compared to postganglionic sympathetic neurons. [8] Postganglionic sympathetic nerves terminating in the kidney release dopamine, which acts on dopamine D1 receptors of blood vessels to control how much blood the kidney ...

  9. Adrenal gland - Wikipedia

    en.wikipedia.org/wiki/Adrenal_gland

    These blood vessels supply a network of small arteries within the capsule of the adrenal glands. Thin strands of the capsule enter the glands, carrying blood to them. [8] Venous blood is drained from the glands by the suprarenal veins, usually one for each gland: [8] The right suprarenal vein drains into the inferior vena cava.
