Skeletal System Case

| - osteoblasts begin to replace the fibrocartilage splint with spongy and compact bone, forming a bulge that is initially wider than the original bony shaft

The skeletal system is a very essential part of the body, without it would be impossible to do many things even moving. The skeletal is composed of bones, ligaments, cartilage, tendons, and other tissues. The skeleton is separated into two regions, the axial skeleton which forms the supporting axis of the body also the appendicular skeleton which includes the bones of the upper limb and pectoral girdle. The main functions of the skeletal system are support, leverage, storage of minerals and lipids, also blood cell production. Each bone or group of bones makes up the structure of the body, allowing soft tissues and other organs to attach to them. The storage of minerals and lipids is also a very important function of the skeletal system. They

Formation of hematoma When any bone breaks it begins to bleed causing a massive formation of a blood clot known as hematoma. Blood capillaries come in the clot and fibroblasts, macrophages, osteoclasts, and osteogenic cells begin to invade the tissue of the fracture. Then granulation tissue fills in the injury. During this stage inflammation occurs, redness and swelling is visible.

In this content am going to be talking and explaining the structure and function of the skeletal system. I will be talking about: Axial skeleton, Appendicular. Also highlighting the different types of bone such as long bones, short bones flat bones, irregular bones and sesamoid bones. I am also going to be talking about how your body is

Longitudinal bone growth occurs at the epiphyseal plate, which is a thin layer of cartilage between the epiphyseal and metaphyseal bone at the distal ends of the long bones. Bone growth is the result of maturation, growth of chondrocytes, their production of bone matrix, and finally calcification (47). The growth plate is a complex structure consisting of different layers of cells, as shown in figure 3. The most immature cells, the stem cells, are found towards the epiphyseal end of the growth plate in the stem cell zone, or resting zone; the proliferating zone contains more mature chondrocytes and the hypertrophic zone contains the larger chondrocytes. The resting stem cells in the resting zone are recruited, whereupon proliferation and differentiation

I have enjoyed reading your post, Kerry. I found your comment on Osteomyelitis informative and thought provoking. As you have stated, Osteomyelitis is an infection of the bone that may start in the bone or may be a result of an infection that has started elsewhere in the body and traveled through the blood stream to the bone. Osteomyelitis may be difficult to treat as it is sometimes located deep in the bone. Osteomyelitis most likely affects long bones in children while affect the vertebrae in adults. Diabetics may develop osteomyelitis in their feet. Osteomyelitis may be difficult to treat; however, it may be treated successfully with strong intravenous antibiotics combined with surgery (Arias, Betancur, Pinzón, Arango, & Prada, 2015). Risk

When a bone is broken the following things happen: a blood clot forms around the break. Inside the blood clot, special cells called phagocytes begin cleaning bone fragments and killing any germs which might have gotten in around the break. Phagocytes are part of the immune system. Next, a soft callus made mostly of collagen is created around the fracture by another special group of cells called chondroblasts. This stage can last anywhere from 4 days to 3 weeks. A hard callus forms next as osteoblast cells create new bone, adding minerals to make it hard. This stage typically begins 2 weeks after the break, and ends somewhere between the 6th and 12th week. Lastly, the bone is remodeled. Special cells called osteoclasts break down extra bone around the fracture until it's completely healed and returned to its original shape. This stage typically begins 2 weeks after the break, and ends somewhere between the 6th and 12th

What causes with can be an infection in the body being carried through the bloodstream into the bone or surgery/open fracture can lead to an infection of the bone. Staphylococcus Aureus is a basteria frequently found in the respiratory tract and on the skin. S-Aureus isn't always pathogenic (Anything that can cause disease, an infectious agent eg. Virus, bacteria, fungus andparasite), Its is known as the common subject for skin infections such as abscesses ( build up of pus within the tissue of the body), Respirtory infections such as Sinusitis (thick nasal mucous, plugged nose and pain to the face, causes may be allergies and infections) and food

Staphylococcus aureus bacteria which is the most common factor causing bone infection. Skin is likely

Bones can become infected with Osteomyelitis through the blood stream by an open fracture or surgical wound. “Only two out of every 10,000 people acquire Osteomyelitis in a lifetime. The condition affects children and adults but in different ways. Certain conditions and behaviors can weaken the immune system increasing an individual’s risk of obtaining Osteomyelitis such a diabetes mellitus, alcoholism, hemodialysis, rheumatoid arthritis, HIV/AIDS, sickle cell anemia, or a lack of blood supply (www.wedmd.com). In children, Osteomyelitis is usually acute and very easy to treat showing signs in the bones of the arms and legs. In adults, Osteomyelitis can also be acute or chronic and can persist due to a reoccurring medical

4.The Hematoma is created to stop the bleeding caused by the fracture of the bone. Without the hematoma a person would lose a dangerous amount of blood within minutes of the fracture.

The natural process of healing a fracture starts when the injured bone and surrounding tissues bleed, forming a fracture hematoma. The blood coagulates to form a blood clot situated between the broken fragments. Within a few days, blood vessels grow into the jelly-like matrix of the blood clot. The new blood vessels bring phagocytes to the area, which gradually remove the non-viable material. The blood vessels also bring fibroblasts in the walls of the vessels and these multiply and produce collagen fibres. In this way the blood clot is replaced by a matrix of collagen. Collagen's rubbery consistency allows bone fragments to move only a small amount unless severe or persistent force is applied.

Bone at the tissue level undergoes remodeling: it is continuously being resorbed and rebuilt (or formed). A negative balance between bone resorption and formation, frequently due to excessive resorption, is the basis of many bone diseases.

A typical bone has a dense and thin yet tough outer layer, called the periosteum. Periosteum consists of an outer fibrous connective tissue layer, and an inner osteogenic layer. The fibrous layer is made of dense and irregular connective tissue containing many strong collagen fibres and fibroblast cells. Fibroblasts produce the collagen fibres and regenerate the fibrous layer as it wears down over time, or is injured by stress to the

The musculoskeletal system is a made up of the muscular system and the skeletal system. The skeletal system provides the internal framework for the body, it protects the organs by enclosing it and anchors skeletal muscles so that the muscles can contract thus causing movement. The skeleton is divided into two divisions: the axial skeleton and the appendicular skeleton (Taylor & Cohen, 2013, p. 94). The Axial skeleton are the bones that have formed the longitudinal axis of the body which is made up of the skull, the vertebral column and the thoracic cage (Taylor & Cohen, 2013, p. 98). The Appendicular skeleton are the bones of limbs and griddles that are attached to the axial skeleton (Taylor & Cohen, 2013, p. 103).
