<reasoning>

Analyze the physiological response to high blood calcium

Using the Bone Cells knowledge point

• When blood calcium levels are elevated (hypercalcemia), the thyroid gland releases calcitonin.
• Calcitonin stimulates bone-building activity to deposit excess calcium from the blood into the bone matrix.

Identify the cell type responsible for bone deposition

Using the Bone Cells knowledge point

• Osteoblasts are the cells responsible for bone formation and mineral deposition (replacing/building bone).
• Osteoclasts function in bone resorption (breaking down bone to release calcium into the blood).
• Therefore, osteoblasts are active when there is excess calcium in the blood to lay down new bone tissue.
