Questions and Answers

What is the main difference between cartilage and bone matrix?

  • Cartilage matrix is firm and pliable, while bone matrix is one of the hardest tissues of the body (correct)
  • Cartilage matrix is avascular, while bone matrix is richly vascularized
  • Cartilage matrix is composed of collagen fibers, while bone matrix contains only elastic fibers
  • Cartilage matrix is non-cellular, while bone matrix is cellular
  • How do cartilage cells receive their nourishment?

  • Via a network of lymphatic vessels within the cartilage
  • By direct absorption from the extracellular matrix
  • Through diffusion from blood vessels of surrounding connective tissues (correct)
  • Directly from blood vessels within the cartilage
  • What type of cells are chondrogenic cells derived from?

  • Epithelial cells
  • Erythrocytes
  • Mesenchymal cells (correct)
