Bone is a mineralized connective tissue. It's a specialized type of connective tissue that's strong and rigid due to the presence of calcium phosphate and other minerals. This unique composition allows bones to provide support, protection, and movement for the body.
Bone tissue is made up of four types of cells:
- Osteoblasts: These cells are responsible for building new bone tissue.
- Bone lining cells: These cells cover the surface of the bone and help to regulate the passage of nutrients and waste products.
- Osteocytes: These are mature bone cells that maintain the bone matrix.
- Osteoclasts: These cells break down bone tissue, which is essential for bone remodeling and repair.
In addition to these cells, bone tissue also contains a matrix of collagen fibers and other proteins that give it its strength and flexibility.
