The Benefits of Exercise on Osteoporosis Many do not think about what makes bones so strong or even think about bones in general. To most bones are just apart of the skeleton, and hold the human body up. But what if the major bones in an individuals body became frail and began to brake from s simple fall? How would an individual maintain a normal life if their bones were susceptible to fracture from small forces? It seems like it would be nearly impossible however, with proper measures this disease

many diseases caused by poor nutrition. One disease young children are at risk for is rickets. Rickets is caused by a vitamin D, calcium, and phosphorus deficiency. Rickets is the softening and weakening of the bones in children. Skeletal deformities and fractures can occur because the bones are so soft and weak. Rickets is seen during periods of rapid growth because during growth a great deal of vitamin D, phosphorus, and calcium are needed. “The predominant cause is a

that is used to inhibit osteoclastic bone resorption .it works by attaching to hydroxyapatite binding sites to impair the ability of the osteoclasts to produce the protons necessary for continued bone resorption. It also inhibit osteoclast activity by promoting osteoclast apoptosis. (pubmed ) Patient group who are mostly taking this medication are postmenopausal women. As women reaches their menopausal age, oestrogen starts to deplete which causes their bones to

Bone formation and bone break down is a very important maintenance of the human body. After tooth eruption teeth move and need new bone to form constantly. Due to the wear of enamel on the interproximal and occlusal surfaces teeth are constantly moving in the mouth. For that reason, Osteoclasts are activated and they begin to breakdown old bone. On the opposite side of the tooth osteoblasts lay down new bone. With age however bone begins to change. When a person is young they have healthy, dense

Osteoporosis is a progressive bone disease that is characterized by low bone mass along with continuous loss of bone tissue with increased fracture risk. The pathology is multi-factorial and there are several modifiable and non-modifiabale factors that contribute to the development of this disease. According to the World Health Organization, osteoporosis is defined as a systemic skeletal disease illustrated by a decrease in bone mass and bone tissue, causing a decrease in bone and a subsequent increase

fracture because of (A) the loss of spongy bone in the epiphyses and (B) the thinning of the bony collar in the diaphysis. 6. Describe the changes that a broken bone undergoes as it is healing. The bony collar of long bones helps them withstand compressive stress by the mechanism described in #4A above (i.e. hydroxyapatite, weight-bearing pillars). In addition, long bones also withstand compressive forces by virtue of the spongy ("cancellous") bone in the epiphyses. The interlocking network

phase "lacking cartilage development." Cartilage is hard and durable but is also a flexible tissue that makes up most of the bone structure during the early stages of development. Nonetheless, in achondroplasia there is no problem with developing cartilage, but instead the problem comes in converting it to bone, a development known as ossification, predominantly in the longer bones of the arms, such as the humerus, ulna and radius, and legs, which include the femur, tibia and fibula. Achondroplasia is

meaning porous bone from the Greek language, is bone disease that gradually and steadily wears down bone tissue and its living cells. This wearing down will eventually cause the cells of bone tissue to degrade and die, leaving their “scaffolding” to be the only things only bone together. Without living cells to take up a home in this scaffolding, minor injuries such as falls, bumping into objects, and pressure that would normally be completely and would not pose any threat to bone tissue suddenly

disease is very painful and quite common in people when they grow old, so therefore it is important to know every aspect from beginning to end. In the joints there are bones, and around the bones there is cartilage and synovial fluid. Cartilage is the a smooth covering that helps the bone move without rubbing bone to bone or bone to joint (2008, schueler). The primary factor here is cartilage. When there is no cartilage it causes intense

and osteochondroma in mice Abstract Introduction Bones are dynamic tissues that undergo a constant cycle of fracturing, resorbing, and remodeling. Bone mass is reflected by the coupled balance of osteoblasts, which produce bone matrix proteins and osteoclasts, which degrade bone (Miyamoto, 2003). This opposite and complementary activity between these two lineages of cells maintains the homeostasis of bone resorption and formation during bone remodeling. Dysregulation of this process is a major
