Study Notes
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)
