    Describing mitochondria without the word "powerhouse"? Blasphemy!



  2. Mortal Reminder on May 17, 2022 at 8:38 pm

    wait is that actually a real limb?



  3. Dean J on May 17, 2022 at 8:41 pm

    I recommend all gym-goers to check out this video, really informative and gets you visualizing muscle movement better when you work out.



  4. JOHN MANDAL on May 17, 2022 at 8:42 pm

  7. Daniel Williams on May 17, 2022 at 8:44 pm

    Jeffrey the skeleton looks more like a she than a he.



  8. joe cunningham on May 17, 2022 at 8:48 pm

    Just done a physio therapy workout and this pops up 5 minutes later XD



  9. Randy Ollmann on May 17, 2022 at 8:49 pm

    The others are smooth muscles and the cardiac muscle



  10. Idrissa Wane on May 17, 2022 at 8:49 pm

    Damn maybe my chicken legs are due to having more percentage of slow twitch fibers :/



  11. TIG2MAN0 on May 17, 2022 at 8:50 pm

    If I can do 40 pushups, would I use slow twitch for first 30. Then when it gets hard would I use fast twitch?



  12. Tomato Sama on May 17, 2022 at 8:51 pm

    are those dead people in the bg?



  13. melloi on May 17, 2022 at 8:51 pm

    Latissimus dorsi



  14. Jeremy Ashcraft on May 17, 2022 at 8:52 pm

    …I could never be a doctor… I find the cadaver is so repulsive to look at…



  15. Chromic Quanta on May 17, 2022 at 8:53 pm

    Smooth and cardiac muscles.



  16. LightEye333 on May 17, 2022 at 8:53 pm

    Would love to see a video covering what fasting does to the body



  17. mskiUSMC on May 17, 2022 at 8:53 pm

    Skeletal, smooth and…. Don’t remember the other.



  18. Herbert von Sauerkraut unterhose on May 17, 2022 at 8:55 pm

    Love muscle?



  19. Valerie Coleman on May 17, 2022 at 8:57 pm

    Smooth and cardiac?



  20. Colin Burgess on May 17, 2022 at 8:58 pm

    great video, gradually expanding the mechanisms involved



  21. Bro Akroze on May 17, 2022 at 9:00 pm

    Cardiac and smooth muscle. Had a unit on this way back in Febuary…
    Cardiac is the heart muscle, whereas smooth muscle controls primarily involuntary actions such as peristalsis, and they aren’t striated.



  22. Idi Nahui on May 17, 2022 at 9:01 pm

    Cardiac and smooth



  23. Jen Capra on May 17, 2022 at 9:04 pm

    It’s cardiac and smooth muscle!!!



  24. Solomon Johnson on May 17, 2022 at 9:04 pm

    I wonder who Jeffery the skeleton was when he still had flesh and life 😞



  25. Turtle gaming / T.3.K on May 17, 2022 at 9:05 pm

    Skeletal muscles, smooth muscles, and cardio muscles



  26. Prashray Mishra on May 17, 2022 at 9:08 pm

    Smooth muscles that control involuntary actions and cardic muscle that are located in the pericardiac chamber and constitutee the heart muscles



  27. EXTRAUDO KNIGHT on May 17, 2022 at 9:11 pm

    Smooth and cardiac are the other 2 muscles found in the body



  28. Tim David on May 17, 2022 at 9:11 pm

  29. TAROTAI on May 17, 2022 at 9:13 pm

    The muscle in the thumbnail looks dehydrated.



  35. Peter Rocc on May 17, 2022 at 9:19 pm

    And as it is appointed unto men once to die, but after this the judgment: (Hebrews 9:27)
    And the times of this ignorance God winked at; but now commandeth all men every where to repent: (Acts 17:30)
    For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death. (2 Corinthians 7:10)
    I tell you, Nay: but, except ye repent, ye shall all likewise perish. (Luke 13:5)
    For whosoever shall call upon the name of the Lord shall be saved. (Romans 10:13)



  36. ali's Garage on May 17, 2022 at 9:21 pm

    Is that an actual human bicep?



  37. Jen Capra on May 17, 2022 at 9:21 pm

    “You can go for miles and miles jogging…” me: 👁👄👁

    LOL love these vids so much. I’m studying for my massage therapy board exams and this is super informative and entertaining:)



  38. Uncle Ruckus on May 17, 2022 at 9:22 pm

    I still can’t get over the casualness of this man just messing with REAL body parts, but then again it’s his job as an outsider it’s absolutely wild



  39. John Smith on May 17, 2022 at 9:23 pm

    Smooth and Cardiac



  40. TIG2MAN0 on May 17, 2022 at 9:25 pm

    These are the best videos on the internet. High school kids should have a class just watching these. The body is the vehicle that carries us through life, its important to know how it works.



  41. Modzeey on May 17, 2022 at 9:27 pm

    Bro I had no interest in the human body but now I’m addicted to watching human anatomy



  42. Denis Yaremchuk on May 17, 2022 at 9:27 pm

    Let’s appreciate that this craze fella killed someone and stripped of a skin from his body to show us the princip of muscles.



  43. Joey Cosentino on May 17, 2022 at 9:28 pm

  44. Arif Rahman on May 17, 2022 at 9:30 pm

  45. Vincent Aryasatya on May 17, 2022 at 9:30 pm

  46. •°Erythro°• on May 17, 2022 at 9:30 pm

    Came to say the thumbnail looks like fried human… I wonder how it tastes…



  47. Valentina Diego077 on May 17, 2022 at 9:31 pm
