called synovial joints‚ which means that they have a cavity in the joints that contains synovial fluid. Joints are not just made of bone‚ because if they were‚ friction would keep them from moving smoothly. The body uses cartilage and the synovial fluid to reduce friction in joints. Osteoarthritis happens when cartilage wears away over time and exposes bone to bone and increases friction‚ which is very painful. Synovial fluid is a fluid-like material that is present in many of the joints of the

T-score of -1‚ meaning Ms Fredrick’s bone density is that of osteopenia. This means that Ms Fredrick’s body is at risk of forming osteoporosis. Ms Fredrick can stop this from happening by quitting smoking‚ eating healthy‚ exercising and considering Hormone Replacement Therapy. As a menopausal woman Ms Fredrick is going through a hormone imbalance. During the menopause the endocrine system produces less of the hormone oestrogen which is important in healthy bone growth (Shaw L 2005). Ms Fredrick is

located behind the thyroid gland. The effects of parathyroid hormone on serum calcium are mediated by increasing renal tubular resorption of calcium‚ increasing calcium absorption from the intestines (via vitamin D) and increasing release of calcium from bone. Through their secretion of parathyroid hormone (PTH)‚ the parathyroid glands are primarily responsible for maintaining extracellular calcium concentrations. Hence‚ overproduction of parathyroid hormone results in elevated levels of plasma calcium

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

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

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
