1. | Muscular dystrophy | An auto immune disorder causing progressive degeneration of skeletal muscle |
2. | Arthritis | Inflamed joints |
3. | Tetany | high Ca2+ level causing rapid spasms. |
4. | Myasthenia gravis | Genetic disorder resulting in weakening and paralysis of skeletal muscle |
1. | Inflammation of joints due to accumulation of uric acid crystals |
2. | Weakening of bones due to decreased bone mass |
3. | Inflammation of joints due to cartilage degeneration |
4. | Weakening of bones due to low calcium level |
