A disease that causes the breakdown of muscle is called what?

• A. Fibromyalgia
• B. Muscular dystrophy
• C. Myasthenia gravis
• D. Rhabdomyolysis

Answer: (D)

Rhabdomyolysis describes rapid breakdown of skeletal muscle tissue, with contents like myoglobin leaking into the bloodstream. The term itself means muscle breakdown, so it directly fits a condition described as causing muscle to break down. This is different from fibromyalgia, which is a pain syndrome without actual muscle destruction; muscular dystrophy, which is a genetic, progressive muscle degeneration; and myasthenia gravis, which is an autoimmune problem that weakens the connection between nerves and muscles rather than causing the muscles to break down. Rhabdomyolysis is the specific process of muscle fibers deteriorating and releasing their contents, which can lead to complications like kidney injury if not managed.
