Detailed

The human body begins to appear after the seventh embryonic week.


The human skeleton is mainly composed of inorganic salts. Both ends of the bone are composed of cartilage. The outside of the bone is wrapped by the periosteum. The periosteum is rich in nerve cells and capillaries. There is a very active bone marrow tissue in the bone. Osteoclasts are constantly working, so that the bones can maintain a hollow structure, and a large number of osteoblasts are continuously accumulating inorganic salt tissues in the outer layer to maintain the growth of bones. Therefore, bones are a huge organic life body. Human bones not only grow from the ends of the bones, but also from the inside of the bones. Human bones have huge growth potential.


From a young age, the ratio of inorganic salts to organic matter in the bones gradually begins to change. In childhood, the bones are soft and elastic. It is also when the body is growing. At this time, the composition of inorganic salts in the bones is relatively small, and the composition of organic growth substances is large. At this time, the internal stress of the human bones is small, and the bones are easy to grow. , but with the increase of age, the proportion of inorganic matter and organic matter in the bone gradually changes, and the properties also begin to change. The proportion of inorganic matter in the human bone gradually increases, and the organic growth begins to decrease. The internal stress increases. Bone growth begins to slow down or even stop. At this time, human bones begin to harden and gradually lose their elasticity. After the bones become hard, they become brittle, so we are more prone to fractures when we are old, and it is very easy to recover after fractures. slow.
