What follows the activation phase in the bone remodeling cycle?

• A. Formation
• B. Reversal
• C. Resorption
• D. Maintenance

Answer: (C)

In the bone remodeling cycle, the activation phase initiates the process of rebuilding bone tissue. After activation, the next phase is resorption, where osteoclasts break down old or damaged bone tissue. This is a critical step in maintaining bone health, as it clears out bone that may be weakened or no longer needed, making way for new bone formation.

Resorption allows for the essential recycling of minerals like calcium and phosphorus back into the bloodstream, which can be utilized by the body as needed. Following the resorption phase, the bone remodeling process progresses to the formation phase, where osteoblasts synthesize new bone matrix.

Understanding the sequence of these phases is vital for recognizing how bones maintain their strength and integrity over time. Therefore, resorption naturally follows the activation phase, making it the correct answer in the context of the bone remodeling cycle.
