Bone Cancer Bone cancer is when there is an abnormal growth in the amount of tissue in a bone. These strange growths can be either benign or malignant‚ but usually malignant. There are two types of bone cancer; primary and secondary. In primary bone cancer‚ the cancer had actually started in the cells of the bone‚ whilst in secondary‚ the cancer has started in a different area and traveled through the body to the bone. The three main types of bone cancer are osteosarcomas‚ Ewing’s sarcomas‚ and

A skeleton is a complex structure of bones. They work together with muscles‚ tendons and ligaments. All these components support the body and enable a large range of movements. The main body is supported by the spine which is made up of small bones stacked one on top of the other and separated by cushions known as inter-vertebral discs. These discs stop the bones from rubbing against each other and also act as shock absorbers. The skeleton forms the

Bone cancer can be primary bone canceror secondary bone cancer. Primary bone cancer started in the bone; the cancer initially formed in the cells of the bone‚ while secondary cancer started elsewhere in the body and spread to the bone. Examples of primary bone cancer include steosarcoma‚ Ewing sarcoma‚ malignant fibrous histiocytoma‚ and chondrosarcoma. According to the National Cancer Institute‚ USA‚ it is estimated that by the end of 2010 there will have been 2‚650 new cases and 1‚450 deaths

Osteogenesis Imperfecta (OI) is a bone disease that is also known as brittle bone disease. It is a genetic disorder that can affect extra skeletal tissues‚ teeth‚ and heart valves. Mostly though‚ this disease affects bones and muscles. The bones become very fragile and very breakable as well as the muscles become very weak. All of these things happen as a result of one out of two genes that carry the instructions for type one collagen‚ this collagen is what carries these deformities. These genes

Heterotopic ossification is the presence of bone in the soft tissue where bone does not normally exist. The ossification process involves the formation of mature lamellar bone‚ which is indistinguishable from normal bone‚ in soft tissues surrounding paralyzed joints (Kedlaya‚ Sheridan 2013) The signs and symptoms are harder to diagnose in a patient that cannot tell you that they have

Title: Bone Mechanics Objectives:- -To become familiar with LabView software and National Instruments‚ in order to record and observe the strain signals from chicken bone and an aluminum rod. Background: Data acquisition is the use of computer software connected to a measuring device. Signals and measurements are recorded‚ which is converted into a digital signal only understood by a computer. Data is recorded at a certain speed that is processed in real time‚ and can be immediately interpreted

Chicken Wing Dissection The chicken wing dissection was very helpful in understanding not only the muscular system but also the skeletal system. We looked at both the bone and the muscles of the chicken wing. We noticed many different things that we had been studying in class. In this dissection we studied structure and function of a chicken wing‚ which is comparable to that of the human arm. First‚ we removed the skin of the wing with the tools provided for us. We examined yellowish tissue clumped

true! Just as we age on the outside‚ our bones grow older on the inside also. Our risk for arthritis‚ osteoporosis and injuries increases with every passing moment. Knowledge of how to care for ourselves is important to reducing our risks. Maintaining proper nutrition is an important element. We have to be sure that our diet is rich in calcium and other important nutrients. Osteoporosis is the most well known condition that affects our bones. “In the early stages of osteoporosis‚ there

The musculoskeletal system includes bones‚ muscles‚ and connective tissues that all work together to provide the framework for the body‚ create body movements‚ store minerals and lipids‚ produce blood cells‚ and protest the body’s organs. The bones‚ muscles‚ and connective tissue comprise approximately sixty percent of the body’s mass. There are 206 bones and about 700 named muscles of three different types: skeletal‚ cardiac and smooth muscles (Taylor). Musculoskeletal disorders consist of minor
