composition of bone mostly consist of inorganic material and collagen fibers. The macroscopic structures of bone is Compact bone‚ Cancellous bone‚ Epiphysis‚ Diaphysis‚ Periosteum‚ Red bone marrow‚ yellow bone marrow‚ and the articular cartilage (Doitpoms.com). Collagen is a triple helix structured protein that is the most prominent protein in the skeletal system. Bones consist of two distinct types of bone tissue such as cancellous and cortical bone. Cancellous bone is also known as spongy bone and is located

Bones support‚ move‚ and protect the body; they also give us our features. But without bone cells we would have no bones. Bone cells are the living units that make up your bones and keep them functioning. Bone cells have two major roles‚ which are the production of new bones and resorption or destruction of old bone. They also carry out other small roles. There are four main types of bone cells: Osteogenic‚ which are bone cells that respond to traumas‚ osteoblasts‚ which form bone matrix around themselves

Identifying a Bone Deformity Identifying a bone deformity is fairly easy if the bone is twisted or curved significantly enough that anyone could visually look at it and see that something is definitely wrong. However‚ sometimes‚ the deformities are less noticeable. In these cases‚ a doctor must do a thorough examination of the limb that is being disfigured. Measurements are taken to compare it with the other matching limb. X-rays and bone density analysis tests are sometimes also needed too. Causes

Lab 34-2: 1. The general trend for bone density as a person ages is a steady decline as years pass. This study shows that every decade‚ males and females bone density slowly decreases. 2. Between the ages of 20-50 females lose about 11% of their bone density and males lose about 13% of their bone density. Males do in fact lose more density then females but they lose it at a more stable and steady rate. Females lose less density at more unstable rate going from about 6% (40-50) to about 9%

Clavicle: it is the insertion of the upper trapezius muscle which is responsible for scapula elevation and extension of the head and neck. 2. Humerus: long bone to which the brachialis muscle is attached at its distal half of the anterior portion of the humerus to help flexion of the elbow. 3.

Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex‚ pose a significant health risk to the patient‚ or fail to heal properly.Bone generally has the ability to regenerate completely but requires a very small fracture space or some sort of scaffold to do so. Bone grafts may be autologous harvested from the patient’s own body‚ often from the allograft or synthetic with similar mechanical properties to bone. Most bone grafts

study the Microstructual influence on fracture resistance in 7000 seriers aluminium alloys. Fracture toughness is an indication of the resistance of a material to physical separation by a process of unstable macrocrack propagation. The microstructural features such as coarse particles of intermetallic (IM) phases‚ dispersoids‚ inter- and intragranular precipitates‚ precipitate-free zones ‚ grain size and orientation are known to exert significant effects on fracture resistance.So this paper focusses
