Osteoclast

No human could function without the osteoblast cell. The responsibilities of the osteoblast include both the mineralization and synthesis of bone. The large cell carries out these jobs throughout the first formation of the bone and then later the remodeling of bone. Osteoblasts have one nucleus and works in teams to build bones and can be found either on the top or next to bone. Out of all three bone forming cell types, osteoblasts are the ones that produce the organic material that makes up…

Osteoporosis is a condition in which the rate of new bone made does not match the levels of bone being broken down. The condition is caused by a range of factors in which effects the levels of new bones made. There are a range of factors that cause Osteoporosis, these are Estrogen: If the level of estrogen drops then bone loss accelerates and can lead to Osteoporosis. Having both ovaries removed in a process known as bilateral oophorectomy, results in low bone density. In the case of males,…

Osteomyelitis Anoimalo S. Matagi Alaska Career College Abstract Osteomyelitis affects about two out of every 10,000 people (Cleveland Clinic, 2016). A possible reason as to why two of 10,000 people are affected is their lack of understanding to how to treat and prevent osteomyelitis. For example, those who are not aware of how osteomyelitis and how it effects the bone, as many organisms (most commonly staphylococcus) travel through the blood stream and can cause a bone…

There are many different forms of dwarfism found all over the world. The most common one however; is called Achondroplasia. Achondroplasia actually means “without cartilage formation”. This does not mean that the body cannot make cartilage. It means that the cartilage is not able to convert into bone. This process is called ossification. Achondroplasia is very similar to another type of dwarfism called hypochondroplasia. The biggest difference between the two is that your features are…

During muscle and bone repair, there will be a natural attempt by the body to heal and repair, this usually presents its self in one of three ways. Regeneration, as the name suggests this is usually in mild cases or injury where very little tissue damage has occurred and the body may naturally be able to regenerate the initial structure. Resolution, this usually occurs following mild inflammation where the body removes dead cells and debris from the affected area, leaving the original non…

Osteochondrodysplasia is a group of unusual hereditary disorders of the bone, connective tissue, or cartilage. In this disorder growth and evolution of cartilage, bone, and connective tissue are impaired. Osteochondrodysplasias can be passed down by the parent to the offspring. This disorder causes the skeleton to flourish abnormally and the results can lead to dwarfism. The chances in someone having osteochondrodysplasia is one in every 4000 to 5000 births. This disorder is not developed as…

Figure 2.3: The structure of bone (Abedon, 2014) 2.1.2 Mechanical Properties Bones is always considered as man-made engineering materials. Due to its synthesis there have more variation in properties than engineering materials. The factors can include as the location in body, mineral content, disease, age, gender and the amount of water that presence in the human body. The mechanical properties of bone tissues must be considered as very hard and lightweight material. Mechanical behavior of…

 Pathophysiology of Osteoporosis Osteoporosis is a condition of skeletal fragility due to progressive loss of bone mass. Losing bone is a normal part of the ageing process, but some people lose bone density much faster than normal. This can lead to osteoporosis and an increased risk of fractures. It occurs in elderly people of both sexes but is most pronounced in postmenopausal women, they lose bone rapidly in the first few years after the menopause (when monthly periods stop and the ovaries…

The musculoskeletal system provides form, support, stability and it is responsible for the movement of the body. The strong protective skeletal layer protects vital organs. For example rib cage protects the heart, kidneys and lungs from any traumatic injury. Bones provide framework that supports and keeps the body from collapsing. It is the major supporting structure of the body. The bone is classified by their shape or structure as cortical bones are dense and compact and cancellous is spongy.…

Osteogenesis Imperfect is also known as the, “Brittle Bone Disease”. This is an extremely rare disease with less than twenty thousand cases a year. As of today there is no known available cure, but there are treatments available to lessen the symptoms of the disease. This is a chronic illness that can last up to a few months, to lasting a person’s entire lifetime. This is a disease that causes extreme fragility in the bones of a normal person. This could make a person’s life extremely difficult…
