    You are quite literally the greatest educator that has ever graced the planet earth. You have a PhD+ level of understanding of every topic you cover, yet you know how to communicate it succinctly and simply. You were born to teach.

    Just a lil correction, the adrenal medulla produces or pumps out 80% epinephrine and 20% Norepinephrine (4:1 ratio)
    Thank you for your beautiful work😍

    An interesting fact about beta blockers is that they can be used as a doping agent on healthy elite sportsmen. During training beta blockers maintain a reasonable cardiac output and muscle perfusion increasing performance as a conditioning agent. During training under normal conditions an increased cardiac output will increase blood pressure only to a threshold where the ventricles need enough time to fill their chambers with blood. If the heart rates increases beyond the threshold the ventricles will fail to pump the 125 ml per contraction. This will reduce tissue perfusion due to a lower mean BP.
    The beta blockers can keep the heart rate below the threshold effectively during training.
    This is why beta blockers are banned in competitive sports and considered a doping agent by the IOC.

    Great lecture overall, but one mistake at 9:48: the adrenal gland secretes epinephrine and norepinephrine at a 4:1 ratio. Thus, 80% of secretion is epinephrine and 20% secretion is from norepinephrine.

    Zach - when you are talking about Alpha1 antagonist drugs on the bladder with BPH (e.g. the -osins), don't you mean the indication is urinary RETENTION (2ndary to BPH) not incontenance? I though the idea was with BPH, we get relaxation by the A1 Antagonists, allowing relaxation at the prostate and internal sphincter, which allows for easier urination...

    • @rajavignesh6749

    • @asjadkarma9285

    • @calloftruth
      @calloftruth Рік тому

      i think alpha 1 inducers retain the urine other hand alpha 1 blockers blocks or stops the activity to treat retention.

    We dont prefer alpha 1 blockers forHTN bcz it decreases BP markedly on working at urinary bladder sphincter by micturition is it right concept so we should prescribe it when HTN+ BHP together

  • @iamsufyanali
    @iamsufyanali Рік тому +1

    Sir, you made a mistake at 9:41 when you tell that NE is the 80% released by Adrenal Medulla while it is the other way around. It is 80% EPINEPHRINE that is released by ADRENAL MEDULLA.

    • @j.b.3543
      @j.b.3543 8 місяців тому

      He made an honest mistake, and you are right, it helps in urinary retention because it relaxes the internal urethral sphincter and thia causes urination

    Hello! Love your videos! I think the notes on the website and the written values on the video might include a typo. In lecture and web searching we are given EPI and (80%) produced and NE (20%) in a 4:1 ratio not flipped as shown in the video. Also the notes you give on the website also show NE being produced by the adrenal medulla twice. Not a huge deal but just wanted to give that feedback. There were some other things with other lectures I have noticed (minor details), and if there is a better way to inform about these please let me know!. Great Stuff all in all though!
