  • Alpha and Beta receptor drug properties are discussed within this video. Always remember you have ONE heart, TWO lungs. Alpha always constricts, Beta always dilates. There are two easy ways for you to remember the effects of these receptors and how they work within the body!

      Bro most of what you said is incorrect and most is correct, the mnemonic is for beta receptors not the Alpha.

  • @sunnybunnysky
    @sunnybunnysky 4 года назад +75

    Beta 1 receptor does not cause dilation of anything, like he said (or vasoconstriction, for that matter). It causes renin to be released from the juxtaglomerular cells in the kidneys, which increases BP and contractibility. Beta 2, on the other hand, DOES cause dilation, both in the bronchioles AND the veins, resulting in a lowered BP.

    Ps. Anybody want to explain how beta blockers effect hypertension using this crayon logic?

    just a little correction, or perhaps, to make it more accurate.
    alpha 1 receptors is present in smooth muscle, and is targeted by meds to block them, to cause vasodilation...the heart does NOT get dilated, as i believe such a medicament would get pulled from the market pretty quickly!
    The "1 heart, 2 lungs" mnemonic is for the Beta-receptors, not for alpha receptor as you mention. B1 in heart, B2 in lungs.
    alpha 1 - smooth muscle/vessels
    alpha 2 - in CNS, post-synaptic receptors, agonism of which will block the sympatetic tone, and cause vasodilation.

      Thank you!! I was about to comment about how this was inaccurate, but you summed it up 10x better than I would've. I'm worried about all these med students in the comments saying, "thank you so much! I finally understand this!" 😳

    • @MeanBeanComedy
      @MeanBeanComedy 4 года назад +1

      Also, I was under the impression that α2 receptors also cause vasoconstriction, since α2 antagonists cause vasodilation. Is that wrong?

    • @skarpengland
      @skarpengland 4 года назад +1

      @@MeanBeanComedy Yes, it is. I am reading from my pharma book, alpha 2 blocks sympatethic tone (not 100% sure of mechanism, but i do believe alpha 2 inhibits alpha 1) either way. stimulating Alpha 2, enhances blockage of sympatethic tone, which yields vasodilation 😊 Alpha 2 agonist is used in hypertension.

      Alpha 2 should inhibit some aspects of 1 and enhance others.
