What impact do glycosaminoglycans have on the extracellular matrix of ligaments?

• A. They decrease hydration and strength
• B. They enhance water retention and stability
• C. They inhibit collagen production
• D. They reduce the tensile strength

Answer: (B)

Glycosaminoglycans (GAGs) play a crucial role in the extracellular matrix of ligaments by enhancing water retention and stability. As components of proteoglycans, GAGs attract water molecules, which helps maintain hydration in the tissue. This increased hydration is essential for the overall function of ligaments, as it contributes to their viscoelastic properties, allowing them to withstand tensile loads while providing flexibility and structural integrity. Moreover, the water retention provided by GAGs helps maintain the overall biochemical environment within the extracellular matrix, supporting cellular activities and contributing to the tissue's stability. This characteristic is vital, as adequate hydration is necessary for efficient nutrient diffusion, waste removal, and proper cellular function, thereby promoting the health and resilience of ligamentous tissues. In contrast, other options neglect the beneficial role that GAGs play in ligament function and fail to recognize their importance in maintaining the structural and mechanical properties of ligaments.
