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

1. Describe bone physiology and the bone remodeling cycle. Be sure to emphasize the two types of bone tissue and the roles of osteoblasts and osteoclasts.

Associated with a large loss of blood. In the case it is the extreme amount of blood lost from her arm wound. Hemorrhage’s can be internal or external

The five functions bones are; to form a sturdy framework for the entire body, protect delicate structures, work as levers with attached muscles to produce movement, store calcium salt, produce blood cells in red bone marrow. The long bone helps with these functions mostly because of it size. Three of aging on the skeletal system are; loss in calcium salts and decreased ability to form protein framwork, cellular metabolism slows, bones are weaker, less dense, and loss of muscle tissue are all effects of aging on the skeletal system.

Osteoblast- cells which build bone by removing calcium and phosphates form the blood in the presence of the enzymes alkaline phosphates secrete by

Soft callus formation Blood clot is replaced by fibrocartilage and collagen, converting granulation tissue to a soft callus. This is where new blood vessels begin to grow.

* Bone injuries and fractures occur when the myeloma cells invade the bone. Osteolytic bone fractures appear as punched out areas on x-ray. Bone pain is experienced especially in the back, pelvis, ribs and skull.

Bone is a living tissue and made up of cartilage. Fibrodysplasia ossificans progressiva bone appears as normal bone tissue, but it develops in the wrong places. Osteogenesis and ossification are medical terms which refer to the formation of bone. Most bones in the human body grow and heal up after a break through endochondral bone formation, which is how FOP bones grow. Cartilage forms first and then the bone will eventually take the place of cartilage.

Each long bone has at least two growth plates. There is one at each end. The growth plate

The outermost layer is a membrane called periosteum, a fibrous connective tissue responsible for protection, connected to fibers called Sharpey’s (perforating) fibers linking to the bone (Marieb, 2012). The external surface at the end of the bone is covered with articular cartilage, reducing joint friction (Marieb, 2012). Within the bone is a thin layer of compact bone called epiphyses, encompassing spongy bone and yellow marrow (Marieb, 2012).

? During fetal development, the bones of the fetus are composed of cartilaginous tissue it resembles osseous tissue but is more flexible and dense because of the lack of calcium salts in its intercellular spaces .As the embryo develops, the process of depositing calcium salts in the soft, cartilaginous tissue occurs and continues throughout the life on the individual after birth.

The pathophysiology of how strong bone becomes osteoporotic is an interesting process. The body is continuously trying to maintain a sense of homeostasis and keep every cell and organ within the body at a constant state of happiness. During the homeostatic process, cells of bone are continuously undergoing processes of formation and resorption. This all-inclusive progression of building up bone occurs throughout life and is the key in modifying bones during trauma or just natural growth (Van der Kamp, 2012). Bone cells that assist with formation of bone are called osteoclasts, and bone cells that assist with the resorption of bone are called osteoclasts.

The bone consists of the diaphysis and epiphysis. The diaphysis is the middle part of the bone and the diaphysis are the ends of all long bones like for example the hip bone. This structure only qualifies for all typical long bones in our bodies. In this disease of osteoporosis cells of bone tissues are also involved such as osteoblasts, and osteoclasts. Osteoblasts are involved in bone forming cells and they secrete calcium and binding proteins. Osteoclasts are involved in dissolving a damage bone and is a way that the bone can be repaired.

Bones is a living tissue that contain a blood vessel and nerves. It capable of moulding itself when it damaged.

Bone serves the organism at multiple levels: As a system, bones permit the organism to locomote effectively and to maintain posture by bearing loads without deformation, by providing rigid attachment sites for muscles and acting as a system of levers to amplify small movements. As an organ, bones protect the viscera and house the hemopoietic tissue (red marrow). As a tissue, bones serve as a reservoir of readily mobilizable calcium, an
