Last issue we learned about that bone, bone attachment and skeletal muscle make up our motor system. On this issue, we would like to talk about the bone which is a sort of framework to support our body under the influence of gravity. Bone is made up of sclerotin, periosteum and bone marrow. To be specific, sclerotin is composed of bone tissue and can be divided into compact bone and spongy bone by structure. The compact bones are distributed on the surface of bone. Spongy bones are like spongy, which consist of interwoven trabeculaes. Trabeculaes are aligned parallel to the direction of stress and tension on the bone, so that the bone can support heavy mass of our bodies. The periosteum is mainly composed of fibrous connective tissue, covering the surface of bone outside the articular surface where is rich in nerves, blood vessels and lymphatic vessels, and plays an important role in the nutritional regeneration and sensation of bone. The periosteum...

  Last issue we learned about the components of our body. So we have already known that the human body can be divided into 10 parts from appearance, meanwhile, many organs can compose 9 systems respectively. On this issue, we would like to talk about the first system of our body, motor system. To be specific, the motor system consists of bone, bone attachment and skeletal muscle, which accounts for about 50 to 70 percent of an adult's body weight. And the motor system performs support, protection and motor functions. The small bones of the entire body are connected in different forms to form regional skeletons, support bodies, protect internal organs, maintain body posture, give the basic structures of the body, and provide broad attachment points for skeletal muscles. The bone is also an important hematopoietic organ. In the meantime, the bones are able to store calcium, phosphorus and other minerals in the body. Skeletal muscle is the power device of the m...
