Final answer:
The statement is true. Forces that reach or exceed a threshold stimulate bone remodeling and new bone formation as described by Wolff's law.
Step-by-step explanation:
True. Forces that reach or exceed a threshold stimulus initiate new bone formation in the area experiencing the mechanical strain, according to Wolff's law. This principle is rooted in the understanding that bone remodeling allows bones to adapt to stresses, becoming thicker and stronger when subjected to stress. For example, athletes often have denser bones in areas exposed to regular, high-impact activity. Conversely, in the absence of stress, such as when a limb is immobilized in a cast, bones may lose mass. This dynamic response of bone cells to mechanical forces is a fundamental aspect of bone modeling and remodeling. When muscles exert force on bones, or when bones bear weight, the mechanical load can stimulate bone tissue to rebuild itself, maintaining or increasing its strength.
