어서 와~ 건강한 나! 19회 ; 뼈가 먼저냐, 골막이 먼저냐, 근육이 먼저냐.?! The Muscle determines Preiosteum and Bone shape.

Hello, I'm Dr. Park Mi-ra, a dentist who pursues truth. Hello, I'm Kim Young-shin, a patient who is curious about the truth. I can't believe that the shape of the bone changes even after the age of 80. I really can't believe it. How can this change happen? Oh, I have to talk about ribs again. Do I have to eat ribs again today? If you look at the ribs, the muscle is what we eat with meat, and the tendon is a little tough. And there's something really hard. Bone skin? I said it too quickly, but I couldn't talk about the bone soup. When you boil the bone soup, it separates from the bone. That's the cartilage. You can think of it as a pouch that holds the bone. Do I have to know the cartilage to know that the bone is changing? Yes, then I'll ask you a question here. Is the bone first or the cartilage first? Isn't the bone first? Oh, that's right. The bone is not first. In fact, the cartilage, the pouch that holds the bone, and the pocket that holds the bone are not determined by the cartilage. Then what determines it? It's complicated. There's a bone in the cartilage. Muscles and ligaments are attached to the surface of the cartilage. In fact, the shape of the cartilage depends on how you use the strength of the ligaments and muscles. It's a pouch made of plastic bags to help you understand. There's only air in here right now. I'll call this plastic bag a cartilage pocket. And you can think of this straw as a muscle or ligament. But the cartilage doesn't look strong at all. That's right. There's nothing you can do about the cartilage. When the muscles and ligaments tighten and loosen, the shape of the cartilage changes. It tightens and loosens. That's right. When the muscles tighten and loosen, the straw acts like this. If you pull it hard, the muscles contract. Then you pull the plastic bag outward. If you pull the straw toward the plastic bag, the cartilage will be compressed. Then the shape of the plastic bag changes. Of course. But this plastic bag doesn't exchange cells. But the human body exchanges cells. Even in this cartilage. Cells are made according to the order of inflammation. They break down, grow, age, and die. But in this process, when the shape of the cartilage is determined by the force of the straw, the bones in the cartilage are determined according to the shape of the cartilage. It's the opposite of what I thought. Is the bone the last? Yes, it's the last. The bone in the cartilage is the same shape as the shape of the cartilage before it receives force. But if the force of pulling the cartilage works, You saw the plastic bag that was pulled earlier, right? Then there's a gap between the bone and the cartilage. Then what happens there? The cells that make the bone go there and fill it up. It's amazing. But why is that? The human body has the property of always maintaining a stable state. It's called instability. If there's an empty space between the cartilage and the bone, it's not stable. And the cartilage has to hold the bone, but it can't. Then what happens to the bone in the cartilage? I think it's going to rattle. Like the sound of putting a coin in a big pocket. Then it's not stable, so it's filled right away. And on the contrary, if the force of pressing the cartilage works, The bone melts and disappears, so the force of pressing the cartilage doesn't work. It's really amazing. I don't think about it in my head and order it. Hey, absorb the bone there. Hey, make a bone there. I'm not doing this. The lives that work in the body are very busy. That's how you maintain your life. Yes, not just the bones, but all organs of the human body. All cells are born, divide, grow, age, and die. I keep doing this over and over again while I'm alive. So even if you're old, you change. Yes, Hyungsin's bones are still exchanging cells. If you're alive, there's always a possibility of change. This is why you didn't have surgery. In the old days, there was a saying that if you're over 40, you have to take responsibility for your face. You're looking at how you've lived. That's right. I think this is the result of what kind of expression this person has lived with, what kind of facial muscles he has used, or what kind of posture muscles he has used. I think this is the result. I can think of it that way. In that sense, where do you breathe if you put one more blood on the roof of your mouth and put your lips up and down? Of course, I'll breathe with my nose. At first, if you put your blood on the roof of your mouth, put your lips up and down, and try to breathe with your nose, it's a little frustrating. But there's another secret to breathing well with your nose. What's that? I'm curious. I'm curious again. I'll explain it to you next time. See you next time. How can I hold it in? I'm curious.
