Bone Structure and Ossification Quiz

Bone Functions

• The 5 primary functions of bone are: support, protection, movement, blood cell production, and storage of minerals
• Bones provide a framework for the body, allowing it to maintain its shape and facilitating movement
• They also protect internal organs, such as the brain, heart, and lungs
• Bones are responsible for producing blood cells, storing minerals like calcium and phosphorus, and regulating hormone production

Bone Composition

• Bone matrix is composed of 65-70% inorganic minerals, mainly hydroxyapatite (calcium phosphate)
• Organic components, such as collagen, make up the remaining 30-35% of the bone matrix

Bone Resorption

• Osteoclasts are the cells responsible for bone resorption, or the breakdown of bone tissue

Human Skeleton

• The adult human skeleton is composed of 206 bones

Bone Cells

• The 3 main types of bone cells are: osteoblasts (responsible for bone formation), osteoclasts (responsible for bone resorption), and osteocytes (mature bone cells embedded in the bone matrix)
