Inflammation of bone and cartilage is described by which term?

• A. Tendinitis
• B. Osteoarthritis
• C. Arthrosis
• D. Osteochondritis

Answer: (D)

This question centers on the terminology for inflammation in musculoskeletal tissues. The suffix -itis signals inflammation, so the term should name both bone and cartilage when describing an inflammatory process affecting both.

Tendinitis is inflammation of a tendon, not bone or cartilage. Osteoarthritis is a degenerative joint disease characterized mainly by cartilage breakdown and bone changes, with inflammation playing a secondary role. Arthrosis is another term for degenerative joint disease, likewise not primarily inflammatory. Osteochondritis, however, uses the roots for bone and cartilage with -itis, indicating inflammation of those tissues. That specific combination correctly describes inflammation involving both bone and cartilage, making it the best choice.
