Which law describes bone adapting to mechanical loading?

Which law describes bone adapting to mechanical loading?

• A. Hooke's Law
• B. Ohm's Law
• C. Darcy's Law
• D. Wolff's Law

Answer: (D)

Bones remodel and become stronger in response to the forces they experience. This adaptive process is described by Wolff's Law: bone tissue reorganizes its structure based on mechanical loading, increasing density and strength where stress is high and allowing resorption where it’s underused. The mechanism involves bone cells sensing strain and coordinating remodeling to optimize stiffness and resilience for typical loads. In athletes, regular weight-bearing and resistance training provide the stimuli that boost bone mineral density and improve bone geometry, helping prevent injuries. When loading is reduced, as in immobilization, bone loss can occur. The other options refer to laws in physics or fluid dynamics and do not describe how bone adapts to mechanical stress.
