← Human Body & HealthWhy does age-related decline in collagen production increase fracture risk more in cortical bone than trabecular bone?
A)Lower turnover masks collagen changes
B)Greater stress absorbs in trabeculae
C)Collagen alignment confers stiffness✓
D)Trabeculae resist collagen degradation
💡 Explanation
Cortical bone relies on the specific alignment of collagen fibers for its strength and stiffness; therefore, a decline in collagen production disrupts this alignment, making it more susceptible to fracture. Trabecular bone's architecture provides more resistance, rather than relying so heavily on collagen alignment, because it absorbs stress through its structure.
