Osteoporosis causes bones to become weak & brittle due to low bone mass & bone tissue deterioration. Chronic & progressive Most common origin of bone disease in U.S. Fractures transpire easily. Primary cause of fractures in elderly. Bone formation should match bone resorption. Osteoblasts Build (form) new bone & generate organic matrix & mineralize bone. Osteoclasts Breaks down bone & cause bone resorption. Osteocytes Maintain bone by directing when/where bone remodeling is to occur. Parathyroid

disease characterized by low bone density‚ which can lead to an increased risk of bone fractures1. Osteoporosis is closely linked to bone remodeling2‚ an adaptive process which maintains bone tissue integrity throughout one’s lifetime3. This process is carried out by specialized groups of bone cells known as basic multicellular units (BMUs) which dictate the processes of coupled bone breakdown and bone formation.3 During osteoporosis‚ this bone turnover rate accelerates and bone remodeling is shifted towards

This is a normal part of ageing‚ but for some people it can lead to osteoporosis and an increased risk of fractures. Other things that increase the risk of developing osteoporosis include: diseases

Bone Marrow Biopsy Introduction Bone marrow is the spongy material found in the center of most large bones in the body. The different cells that make up blood are made in the bone marrow. Bone marrow produces red blood cells‚ white blood cells‚ and platelets. Along with a biopsy (the sampling of mostly solid tissue or bone)‚ an aspiration (the sampling of mostly liquid) is often done at the same time. * Why the procedure is performed: A bone marrow aspiration and biopsy procedure is done for

Project 1.2.3: Bone Detectives Introduction When we think of bones‚ we most often think of the way in which these hard structures support the body‚ how they work with muscles to produce movement and how they protect our internal organs. But the 206 bones of the human skeleton can also tell a story. The specific structure of your bones reveals information about your gender‚ your height‚ your age and even your ethnicity. These biological clues are often the first pieces of evidence scientists
