    Hey! I just wanted to thank Armando (and if anyone else is behind this channel) for all your help over the years. I found your videos when I was studying for AP Biology in high school and they’re just as helpful now as I prep for interviews for my masters. Learning how to make my notes more like your videos is honestly a huge part of why I’m still in life sciences today!!

    Dear Armando
    Im seriously in love.... With your videos... They're so amazing. Your video on beta oxidation of fatty acids actually gave me an A++ on my seminar... Thanks... Byt the way.. I dont remember which video exactly, but it was something from endocrinology.. You said you didnt know about the function of one of the two hormones- calcitonin or calcitrol... I dont remember, sorry... But i do know they both are antagonistic hormones i guess.. Work in the regulation ofcalcium level in bone and blood...... Please do post some more endocrinology videos... We'll love it.. Thanks Armando.

    One comment though:
    PTH in small concentrations will stimulate bone turnover
    continuous concentration of PTH will put Ca++ out the bone
    In the short run Vit D will stimulate PTH, in the long run it will decrease PTH production...

    the lecture is so great tnks aramndo...but i noticed a mistake in osteoclast the bone release both po4 and calcium so the action of pth on osteoclast increase both po4 and ca unlike the action of pth on the kidney cos in the renal system pth favours the excreation of po4 and reabsorption of ca.

    At 8:16 you stated that if the body senses "low plasma calcium" it will stimulate the thyroid to secrete calcitonin. Did you mean "high calcium levels?" I am confused. Is this a verbal error? I thought calcitonin had an opposite role of parathyroid hormone and 1,25 vitamin D OH?? On the chart you have a drawing of plasma calcium in relationship to calcitonin with an arrow pointing up. At 2:45 you say the body senses high concentrations of calcium in the plasma so the thyroid gland secretes calcitonin which helps lower calcium concentrations in the body.

    • @BlueSky-lc4gx
      @BlueSky-lc4gx 3 роки тому

      You are right there was a mistake the correct is that when the plasma calcium is high thyroid gland will release calcitonin to decrease it but when calcium level is low in plasma there will be secretion off parathyroid hormons .

    Amazing work!!! One question: osteoclasts activity on the bone tissue does increase serum phosphate level as well? How is phosphate regulated? Isn't it like calcium regulation?

    • @brittanyrouse2859
      @brittanyrouse2859 9 років тому +2

      I know you asked this a year ago, but I can answer this! So osteoclasts make FGF-23 which is what regulates phosphate. FGF-23 is a hormone that acts on the kidneys to decrease NPT2 (sodium phosphate cotransporter 2). When you decrease this transporter the only place phosphate has to go, is into the collecting duct to be excreted! Hope that helped!

    There is one mistake.... at 8:12 - 8:16 , you said If the body senses low amount of calcium, then it secretes Calcitonin.... Actually its opposite..
    Though the arrows which you hav drawn are correct....

  • @edris.alkozi
    @edris.alkozi 6 років тому

    There is one using wrong word and should be high level of calcium not low level of calcium cause as you know in high level of calcium calcitonin has to be secrets. If you take look in video in 8:11 you will notes it instead of low calcium should be high level of calcium just friendly amendment. the rest is very good explanation.

    This is not quite correct .PTH effect on Git is only indirect thru bit D and calcitonin has no effect on kidneys or Git .only osteoclasts have receptors for calcitonin and thru its receptors calcitonin inhibits osteoclasts activation and and stops new formation ( Guyton and katzung)

    @alsh123am3 8 років тому +4

    Sry but Calcitonin and PTH are both having the same influence on the kidneys... they lead to a decrease of Phosphatresorption and an increase of Calciumabsorption.
    Indeed they are antagonists in the bones but NOT in the kidneys... in the kidneys they work as synergists.

    I love that Vitamin is discussed (D3). But what of Vitamin K2 ? D3 should never be supplemented without its cousin helper Vitamin - K2. This Fat Soluble Vitamin (as I understand it) is essential. AND, without it Calcitonin related calcium activation proteins do not get "Activated" essentially gumming up the metabolic works blocking proper metabolism of calcium (from blood to bones, teeth etc) The chronic lack of Vitamin K2 (true in western diets) is now being thought to be associated with ALL the Calcium related metabolism issues and show up today as very familiar modern ailments (e.g., calcification of arteries, osteoporosis etc...) I do love all your videos. Very, very informative. Thanks!
