Final answer:
Wolff's law describes how bones change their form to better fit their function in response to stress, leading to bone remodeling that can result in bones becoming thicker and stronger with stress. Hooke's law relates to the proportional deformation of materials like tendons and bones under the application of force.
Step-by-step explanation:
The law that states when stress is placed on a bone, it undergoes a tissue reaction whereby its form may change to fit its function is known as Wolff's law. According to Wolff's law, bone remodeling allows bones to adapt to stresses by becoming thicker and stronger when subjected to stress. Conversely, bones that do not receive normal stress, such as when immobilized in a cast, will start to lose mass. This law is critical in understanding how bones heal and the process of bone enhancement with exercise and training, as well as the deterioration during inactivity or microgravity conditions like those experienced in space.
Looking at biological elasticity, Hooke's law describes how the deformation of materials such as tendons and bones is proportional to the applied force. Tendons, for example, show a nonlinear stress-strain relationship, initially stretching easily with applied force and then offering a greater restoring force with a greater strain. Ligaments function similarly, accommodating strain and providing support within certain limits of force and deformation.
