Explain the disorders of skeletal system.

Explanation

Arthritis and osteoporosis are the major disorders of skeletal system.
(i) Arthritis : Arthritis is an inflammatory (or) degenerative disease that damages the joints. There are several types of arthritis.
(a) Osteoarthritis : The bone ends of the knees and other freely movable joints wear away as a person ages. The joints of knees, hip, fingers and vertebral column are affected.
(b)Rheumatoid arthritis : The synovial membranes become inflamed and there is an accumulation of fluid in the joints. The joints swell and become extremely painful. It can begin at any age but symptoms usually emerge before the age of fifty.
(c ) Gouty arthritis or gout : Inflammation of joints due to accumulation of uric acid crystals or inability to excrete it. It gets deposited in synovial joints.
Osteoporosis : It occurs due to deficiency of vitamin D and hormonal imbalance. The bone becomes soft and fragile. It causes rickets in children and osteomalacia in adult females. It can be minimized with adequate calcium intake, vitamin D intake and regular physical activities.
