What term describes tissue's resistance to load?

• A. Elasticity
• B. Stiffness
• C. Ductility
• D. Hardness

Answer: (B)

Stiffness describes a tissue’s resistance to deformation under load. When a force is applied, stiffer tissue deforms less for the same load, and this relationship is captured by k = F/ΔL (the amount of force needed to produce a given displacement). The higher the stiffness, the smaller the deformation. This is separate from elasticity, which is about returning to the original shape after the load is removed; ductility refers to how much permanent deformation a material can undergo before failure, and hardness relates to resistance to surface indentation rather than overall deformation under a load.
