Cartilage Degeneration · Histology

Which structure helps distribute mechanical stress in healthy cartilage but fails during degeneration?

  1. Proteoglycan network
  2. Nerve fibers
  3. Blood vessels
  4. Perichondrial network
Show answer and explanation

Correct answer: Proteoglycan network

Proteoglycans retain water and allow cartilage to resist compressive forces. Degeneration reduces proteoglycan content, weakening cartilage resilience.
