Which minerals are stored in bones?

Which minerals are stored in bones?

• A. Calcium
• B. Calcium and phosphorus
• C. Phosphorus
• D. Magnesium

Answer: (B)

Bones act as a mineral reservoir, with the two key minerals stored there being calcium and phosphorus. They combine to form hydroxyapatite crystals, which give bone its hardness and strength. Storing these minerals in bone helps keep blood levels balanced for essential functions like nerve signaling, muscle contraction, and energy metabolism, and allows minerals to be released when needed during processes such as bone remodeling. Magnesium is present in bone too, but it is not the primary mineral stored there, whereas calcium and phosphorus are the main minerals.
