Final answer:
Wolff's law predicts that bone structure will adapt based on the mechanical forces it is subjected to, leading to bone remodeling that results in either stronger bones with increased stress or loss of mass when immobilized.
Step-by-step explanation:
According to Wolff's law, bone is shaped by the forces placed on it or the lack of force as in immobilization. Wolff's law states that bone remodeling allows bones to adapt to stresses by becoming thicker and stronger when subjected to stress. Conversely, bones that are not subject to normal stress, such as when a limb is in a cast, will begin to lose mass. Moreover, bones do not typically fracture due to tension or compression but usually due to sideways impact or bending, which causes the bone to shear or snap. The behavior of bones under various forces is critical because it determines the load that the bones can carry. Weight-bearing bones, much like the columns in buildings or trees, have special features that allow them to support the weight. Addressing the importance of mechanical forces in bone modeling and remodeling, Wolff's law predicts that bones will modify their structure to withstand the pressures they encounter during normal activities or in response to increased demands such as exercise.
