determine the type of movement that will occur at that location. Each joint contains components of the skeletal and muscular systems and connective tissues that function together to allow movement to occur. A ball-and-socket joint is one example of a synovial joint. In a ball-and-socket joint‚ the round head of one bone rests within a cup-shaped depression in another bone (Martini and Bartholomew‚ 2010). This joint is found in the shoulder and hip of the body‚ and allows the arm and leg to move in a

by the synovium and then inflammatory molecules are released in response to the degradation. Inflammation causes swelling which creates the synovial membrane to thicken and the cells of the membrane to enlarge abnormally‚ vascular flow is interrupted and between the hypertrophy and lack of proper circulation the body experiences metabolic acidosis. Synovial cells react to acidosis and release enzymes that cause the breakdown of articular cartilage and inflames the surrounding tendons and

The Aging Musculoskeletal System When the bones lose mass and become brittle it is called osteoporosis. Loss of bone density accelerates in women after menopause. Mrs. Smith is an 84 year old thin‚ small boned woman. Muscles‚ bones and joints are affected by the ageing process. Osteoarthritis‚ osteoporosis and rheumatoid arthritis are more common in older people. Exercise to increase muscle and bone fitness can reduce or reverse the risk of disability and disease. Some age-related changes‚ such

Part 1 There are 5 individual different types of bone in the human body‚ first we have long bones‚ some being the longest bones available in the skeleton such as the tibia and femur but are also some of the smallest bones such as the metacarpals and metatarsals. The description best suited to long bones would be that they are longer in length than they are in width‚ with epiphysis at either end. (The bones growth plates). The inside of the bone is a spongy like substance known as cancellous bone

Osteoarthritis (OA) is a degenerative disease that manifests without systemic manifestation or acute inflammation. Moreover‚ OA may occur as an idiopathic (primary) or secondary disorder. The primary cause is known. The secondary causes are related to joint damage or causes joint instability. Furthermore‚ OA site typically affects the hip and knee. Patient’s age‚ and body weight play a role in the development of OA. The onset of OA is at 45-year-old and older. OA usually affects joints asymmetrically
