The Cartilage Quiz

• Chondrocytes synthesize and maintain the extracellular matrix of hyaline cartilage.
• Chondrocytes can be singular or in isogenous groups, which represent recently divided cells.
• Newly divided chondrocytes produce matrix material and secrete metalloproteinases to degrade cartilage matrix.
• 60-70% of cartilage's wet weight is water and inorganic salts, providing resilience and lubrication.
• The remaining constituents are structural macromolecules: collagens, PGs, and non-collagenous proteins.
• 40-70% of cartilage's dry weight is collagen.
• Type II collagen accounts for 90-95% of the collagen in hyaline cartilage.
• Type II collagen forms a fibrillary meshwork that provides tensile strength and shape.
• Cartilage properties vary with age and location.
• Metalloproteinases allow chondrocytes to expand and reposition within isogenous groups.
