The Importance Of Bone

Calcium and phosphate ion are deposited into the matrix, leading to hardening of the bone. Osteoblast undergo apoptosis, become encased within the mineralized matrix to become osteocytes or evolve into bone-lining cells. The osteocytes maintain communication with each other and likely played the role in sensing the areas that need to be remodelled, transmitting information to other cells, and initiating the bone-remodelling process. However, as we age daily remodelling

The musculo skeletal is made of bones, muscles, ligaments and tendons. The purpose of the musculo skeletal system is to protect , support and the overall function of the internal structures and organs of the body. Allow movement, give shape to the body, producing blood cells, storing calcium and phosphorus and producing heat. The skeletal system is made of bones and joints. The skeletal system provides the basic supporting structure of the body.

Third, hard callus forms when osteoblasts produce trabeculae and the callus is replaced by this bone. Bone will continue to grow and thicken. Finally, remodeling is the final phase of fracture repair. During the final phase osteoclasts remove excess bony material from both exterior and interior surfaces. Compact bone is now replaced by primary bone.

P4 – Describe the three structures of the skeletal muscle (Epimysium, Perimysium and Endomysium) There are three structures of the skeletal muscle: Epimysium is a thick layer of irregular connective tissue that pulls the entire muscle as well as protecting the muscle from friction that may be caused by other muscles and bones surrounding them. Also, it is the fibrous tissue which covers and surrounds skeletal muscles. The Epimysium carries on past the end of bones in order to create muscle tendons. Perimysium surrounds a bundle of muscle fibres, it is a casing of connective tissue. Endomysium is found within a muscle and it contains nerves and capillaries.

The Nutrient artery enters the shaft of long bone through Nutrient foramen and it traverses obliquely through the canal in the shaft. In tibia, nutrient foramen is directed towards distal end (Figure-1). It will supply the inner half of the cortex, metaphysis and the medullary cavity in the shaft of long bone. The tibia is weight bearing strong medial bone of the leg. Nutrient artery of tibia arises from either posterior tibial artery, anterior tibial artery or its branches at the level of the popliteal bifurcation (1, 2, 3).

Smooth muscle tissues are involuntary muscles in walls of hollow organs, blood vessels, as well as all other body locals where muscles perform their functions. Muscle tissue supports the cell theory as it is composed of one or more cells as well as the energy flow in relation to the energy released through use of muscles during

The Axial Skeleton is the central core of the human body and it protects all the vital organs. It consist of 80 bones in total, 29 bones in the head, 25 bones of the thorax and 26 bones in the vertebral column [8]. The best example for the support and protection function axial skeleton is your skull. There are eight bones in your skull called cranial bone they are thick and hard and lack the ability to move on their own. Their purpose is to protect your brain and its nerves and blood

The growth hormone stimulates cells to produce growth factor (IGF-I). The IGF-I causes cartilage cells to multiply and the old cartilage is transformed into bone. Malfunction in the growth process For a normal growth, many factors are important. If only one component is disturbed, the whole growth process is in the knot and the body is no longer growing. Various influences can interfere with the growth process, both in hormone management and diseases or other external

periostitis Inflammation of the disease Periosteum (periosteum) by the dense connective tissue composition, covered in addition to the articular surface outside the bone surface, and many fiber bundles into the bone. In addition, the tendons attached to the bone, the ligaments attached to the periosteum are attached together. So the periosteum and bone binding are very firm. Periosteum is rich in blood vessels, nerves, through the bone of the trophoblast distribution in the bone and bone marrow. Bone marrow and bone cancellous mesh is also lining a layer of meager connective tissue membrane, called endometrial (endosteum), periosteum inner layer and bone endometrial differentiation of osteoblasts and osteoclasts ability to form a new Bone and destruction, transformation has been generated bone, so the occurrence of bone, growth, repair and so on is of great significance.

• Osteoclasts are used to break done bone matrix and prevent a build up of too much of it and also helps bones to maintain a proper shape. These two cells found the in bones also deposits or removes minerals from the bones, and also help control the amount of these minerals in the blood. Osteosarcoma is the most common type of cancer that develops in bone ("Osteosarcoma | Osteosarcoma Causes, Treatment, Cure, Symptoms, Prevention | Modasta", 2017). The cells that are involved in causing this type of cancer are like the osteoblasts in normal bone, the cells that form this cancer make bone matrix. Therefore, the bone matrix of an osteosarcoma is not as strong as that of normal bones because most of osteosarcomas happen in children and young adults.
