- The structure of human long bones is like a straw, and the middle is empty. When the bones are straightened, they are stronger and more fragile. The softest part is located at the junction of the two ends of the bone , called cavernous bone . As shown in the figure, taking the vertebrae as an example, the hard bones around it are also called cortical bones, and the inner part of the building's beams and columns is sponge bone . The functions of the cancellous bone and the cortical bone are different. For example, only the cortical bone is in the middle of the wrist and thigh bones, but the cavernous bone appears at the ends. And he was very soft and fragile. Strong external forces can easily break the cancellous bone and cause fractures as we know it. However, after the artificial exercise in the day after tomorrow, you can avoid this kind of harm, such as hard qigong.
