A6 - Additional Factors Affecting the Skeletal System Flashcards
What is arthritis?
common disease of the skeleton and can affect people of all ages.
What are the two common types of arthritis?
osteoarthritis and rheumatoid arthritis.
What is osteoarthritis?
osteoarthritis causes the articular cartilage to thin, which would cause pain and lack of mobility at the joint. This would make it difficult to exercise. Mainly develops in those over 40, but can occur at any age.
What is rheumatoid arthritis?
rheumatoid arthritis causes inflammation of the joints so they become painful and swollen. The synovial membrane of the joint becomes inflamed, due to a build-up of fluid. Although the inflammation can be reduced, the joint capsule has been stretched making the joint less stable. Pain at the joint and, later, the increased risk of deformity at the joint will make activity difficult. Normally develops between the ages of 40-50; women are more likely to get this condition then men.
What is osteoporosis?
osteoporosis is the reduction in bone density. It can be caused by a lack of calcium, vitamin D and a sedentary lifestyle. The reduction in bone mass makes the bone more brittle, with increased risk of fracturing a bone from even a minor bump or fall.
What are the benefits of regular exercise?
higher levels of weight-bearing physical activity can reduce age-related bone loss by putting gentle stress on the bones; not too much that they fracture, but enough so that new bone growth is encouraged.
Why is strength training bad for young children?
it can negatively affect bone growth.
How can arthritis be prevented?
regular exercise.
How can osteoporosis be prevented?
as well as regular exercise, resistance training is a good method of preventing osteoporosis, as overloading the skeleton will increase bone density.
