Which tissue type forms the supportive framework of the body and stores minerals?

• A. Muscle tissue
• B. Nervous tissue
• C. Epithelial tissue
• D. Bone tissue

Answer: (D)

Bone tissue is a mineralized connective tissue that forms the body's rigid framework and serves as a major storehouse for minerals like calcium and phosphate. Its matrix is hardened by hydroxyapatite crystals, giving bones their strength, while collagen provides toughness and a slight flexibility. Specialized cells—osteoblasts build bone, osteocytes maintain it, and osteoclasts resorb it—allow ongoing remodeling to adapt to load and to regulate mineral release into the bloodstream. This combination of structural support, protection of organs, and a dynamic mineral reservoir explains why bone tissue best fits the description. Other tissues (muscle, nervous, epithelial) do not provide a rigid framework or serve primarily as mineral storage.
