Study Notes
Bone Cells and Tissue
- Osteoprogenitor cells proliferate and differentiate into osteoblasts.
- Bone tissue is characterized as being highly vascularized, dynamic, and adaptive.
Functions and Locations
- The periosteum's main function is to provide a site for muscle attachment and to serve as a point of entry for nerve and blood vessels.
- Active osteoblasts and osteoclasts are found on the surface of bone tissue, particularly in areas where bone remodeling is active.
Bone Matrix Composition
- The solid matrix of bone tissue is primarily composed of hydroxyapatite, a type of calcium phosphate.
