    My two hours lecture about this was nowhere as helpful as this video, thanks!

      Without a doubt! This channel is so underrated! I've included this channel in a Top 10 Biomedical TH-cam channels video because it very well deserves it to the max!

    This is a very complicated mechanism that you get to see in 2 pictures in books. Thank you for making it very very dynamic and easy to understand! Now I can totally understand the silly diagram I had in my book

    I have no words to say how grateful I am for all your videos! I am an online student and sometimes this information in books is really difficult to understand. SO happy I found you. THANK YOU!

    you explain things better than the professors at my school. I mean we have really good professors but sometimes hearing someone else explain it in a different way helps. It went over my head in class, glad my professor posted this video on blackboard.

    I love the animation og especially explanation in the end on how myosin continously pulls actin. I always thought it was only one pull, but this makes so much more sense now! Thank you sir, I wish you a very good day

  • @Anonimowany1

    Insane to think that all these steps and much more from, conscious thought to neurone action potencials being transferred throughout a whole neurone to the musculature, all the Na and Ca and K transportations, then Calcium being released from SR, then Calcium binding to Troponin, then it rotating, then Myosin binding to Actin, then the whole ATP-cycle, then all these ADP+Pi cycles and so on and so on.
    --
    All this happening several times with just one Myosin for a single contraction withing 0.2 milliseconds?? Insane.

    Excellent. Just a note it's not the myosin that "contracts" so much as the components of the sarcomere that are brought closer together.

  • @lduranceau8046
    @lduranceau8046 3 ปีที่แล้ว

    Can you take a few minutes and try to answer my question: If a person
    wants to throw a football, that person will grip the ball and then bend
    his right (or left) arm, bend the arm backwards, and finally release
    and throw the ball. the bending action is supposed to accumulate power
    for the throw. Can you explain this in the same kind of language you
    used to explain how muscles work?

    • @CatalystUniversity
      @CatalystUniversity  3 ปีที่แล้ว

      When the arm bends back it, the muscles such as subscapularis, triceps brachii, etc. are stretched, which causes buildup up potential energy at the microscopic muscles. Literally, the elastic parts of the tissue are stretched, which builds up potential energy. On the throw, the muscle activate as normal. Also the built up potential energy is converted to kinetic energy and added to the force produced by the muscle: a greater overall force. This only works when the motion is fast, like a throw. It is essentially plyometrics.
