Bone mass is maintained when which two phases are balanced?

• A. Formation and maintenance
• B. Resorption and formation
• C. Consolidation and resorption
• D. Deposition and reorganization

Answer: (B)

Bone mass is maintained when there is a balance between resorption and formation. In the context of bone physiology, resorption refers to the process by which bone tissue is broken down, and its minerals are released into the bloodstream. This is primarily carried out by cells called osteoclasts. On the other hand, formation refers to the building of new bone, a process performed by osteoblasts. For bone mass to remain stable, the rate of bone resorption must equal the rate of bone formation. If resorption exceeds formation, there will be a net loss of bone mass, leading to conditions such as osteoporosis. Conversely, if formation exceeds resorption, it will result in a net gain of bone mass. Therefore, achieving a dynamic equilibrium between these two processes is crucial for maintaining healthy bone density and overall skeletal integrity.
