Here are the essential concepts you must grasp in order to answer the question correctly.
Bone Remodeling
Bone remodeling is a continuous process where old bone tissue is replaced by new bone tissue. This process is crucial for maintaining bone strength and integrity. When there is a lack of mechanical stress on bones, such as during extended periods of inactivity, the remodeling process can become imbalanced, leading to bone resorption outpacing formation, which contributes to degenerative changes.

Mechanical Loading
Mechanical loading refers to the forces exerted on bones during physical activity. These forces stimulate bone formation and help maintain bone density. Inactivity reduces mechanical loading, which can lead to decreased bone strength and density, making bones more susceptible to degenerative changes and conditions like osteoporosis.

Osteoporosis
Osteoporosis is a condition characterized by weakened bones and an increased risk of fractures. It often results from prolonged inactivity, hormonal changes, or nutritional deficiencies. Understanding osteoporosis is essential in the context of inactivity, as the lack of physical activity accelerates bone loss and contributes to the degenerative changes observed in the skeleton.
