What are the main components that make up bone?

• A. Water and proteins
• B. Only minerals and cells
• C. Minerals, proteins, water, cells, and macromolecules
• D. The majority is comprised of water

Answer: (C)

Bone is a complex tissue composed of several key components that work together to provide structure, support, and functionality. The primary components of bone include minerals, proteins, water, cells, and macromolecules. Minerals, such as calcium and phosphorus, are critical for providing the hardness and rigidity that bones need to support the body and resist deformation. The mineralized matrix allows bones to bear weight and withstand stresses. Proteins, particularly collagen, form the organic part of the bone matrix and provide tensile strength, helping to maintain the overall integrity of bone alongside the minerals. Water is also an essential component, making up about 20% of bone tissue, and is important for maintaining the hydration of the bone matrix and helping with the transport of nutrients. Additionally, various types of cells play crucial roles in bone maintenance, remodeling, and repair. These include osteoblasts (which form bone), osteocytes (which maintain bone tissue), and osteoclasts (which resorb bone). Macromolecules, such as glycoproteins and proteoglycans, contribute to the structural integrity and functionality of bone by facilitating the interactions between cells and the mineralized matrix. Thus, the combination of all these components—minerals, proteins, water, cells
