    amazing video, it helped a lot thank you!
    But, there's a small mistake.
    Nuclei is when you're referring to the plural form of NUCLEUS
    therefore you should say 1 nucleus and 2 or more nuclei.
    Apart from that- amazing video thank you!

    I watched your clip a couple of times to help me for an exam on types of muscle tissues, which I found very helpful. On the day on exam, I was able identify the skeletal muscle tissue, label and state function; furthermore I mentioned that it was the fastest moving muscle tissue. However my teacher said it was wrong (he said cardiac muscle tissues is the fastest).
    I tried to look in books and internet cant find the answer,WHICH IS THE FASTEST MUSCLE TISSUE????

    • @borispetkov5079
      @borispetkov5079 10 років тому +3

      From my understanding of your statement, you want to know which muscle type out of skeletal and cardiac has the shortest contraction time. i.e the shortest time from the moment the muscle produces force in response to increased intra-cellular calcium to the re-absorption of Ca into the SR to dismantle the cross bridges and relaxation of the muscle. This is called a twitch, the brief mechanical contraction induced by a single action potential. If you agree so far, then we are looking for the muscle type that facilitates the fastest twitch response. That being the Type two fast twitch skeletal muscle at around 100ms. The cardiac around 300ms. All info is from my physiology lectures at med school :) I hope this has helped.

    Are the muscles in your lungs voluntary or involuntary?

      the respiratory diaphragm is the muscle that controls/deals with breathing, it can be voluntary, but it is also activated involuntarily most of the time

    • @523101997
      @523101997 8 років тому +1

      galikazoid yeah, also the lungs arent really a muscle, oxygen and carbon dioxide travel by diffusion, which of couse is involuntary
