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 looked back on the history of anatomy. In this issue, we would like to talk about the components of our body, especially the systems of our body. The human body can be divided into 10 parts from the appearance, and each part can be subdivided into several small parts. Important parts of the human body are: head (including cranium, face), neck (including neck, nape), back, chest, abdomen, perineum (after four parts collectively called the trunk cadres) and left, right upper limbs, and left, right lower limbs. Cells are the basic units of the body. Cells and intercellular substance constitute organizations. The body's basic organization includes epithelial tissue, connective tissue, muscle tissue and nerve tissue. Several organizations together to form organs. According to different functions, many organs composes 9 systems respectively: motor system for movement of the body; digestive system f...
