Protection: surrounds the brain‚ spinal cord‚ and vital organs. Movement: bones are levers for muscles. Minerals: bones store calcium and phosphate. 2. Compare the axial skeleton with the appendicular skeleton. Axial: forms the long axis of the body and include the bones of the skull‚ vertebral column and the rib cage. Appendicular: consists of the bones of the upper and lower limbs and shoulders and hip bones. 3. How are bones classified? Provide examples. They are classified by their shape:

developmental anomalies can also be used for this purpose. The occurrence of Inca bone occurring due to a persistent Mendosal suture‚ though rare‚ is one such variation in humans. The knowledge of Inca bone in human skull is useful in identifying an unknown. We report a case of incidental finding of true inter parietal or Inca bone in an adult human skull. Key words: Mendosal suture‚ inter parietal bone‚ Inca bone‚ identification. Introduction: Identification is an important aspect of Forensic investigations

language is cancer. Many children and adults of all ages can be diagnosed with a rare type of bone cancer each year. The harmful effects of this disease cannot only be detrimental but deadly too. Thus‚ with early detection‚ diagnosis‚ and proper treatment‚ individuals have a better chance of survival when treated early. First‚ bone cancer is a deadly disease that consists of malignant tumor that forms in the bone. It can also destroy normal and healthy tissue. Any individual can be at risk for developing

Bone marrow transplantation Bone marrow transplantation is a process used to transfer a soft inner part of bone tissue from donor to recipient. It used for patient with certain leukemia or hematopoietic disease. Bone marrow transplantations prescribed to substitute a mal functioning patients bone marrow with a healthy donated marrow that histologically compatible to patient body to insure the maximum beneficence. Bone marrow aspired from donor then treated and frozen till the recipient is ready

Osteoporosis is a bone disease in which the bones become very brittle and weak. Even a little cough could fracture your bone. Causes: when you’re in your younger ages you constantly make new bone how much you store when you reach your peak can determine whether or not you develop osteoporosis. Risk factors of this disease are: • Your Sex‚ in which women are most likely to get it than men. • Your age‚ as you get older your body stops making “new bone”‚ so you will have a greater chance in getting

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

What causes osteoporosis? In childhood‚ bones grow and repair very quickly‚ but this process slows as you get older. Bones stop growing in length between the ages of 16 and 18‚ but continue to increase in density until you are in your late 20s. From about the age of 35‚ you gradually lose bone density. 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
