Bone Tissue

Functions of Bone Tissue

• Functions of bone tissue include support, protection, movement, mineral storage, and blood cell production.
• Not a function of bone tissue: detoxification of harmful substances.

Components of Bone Matrix

• The main component of the bone matrix is collagen, which provides strength and flexibility.
• Hydroxyapatite, a mineral, contributes to the hardness and structure.

Osteoprogenitor Cells

• Osteoprogenitor cells are found in the periosteum and endosteum, crucial areas for bone growth and repair.

Bone Cell Types

• Osteoblasts are responsible for the formation of bone matrix, synthesizing and secreting collagen and other components.

Functions of Osteocytes

• Osteocytes maintain bone tissue and detect mechanical stress, playing a key role in bone remodeling.

Non-calcified Ground Substance

• The non-calcified ground substance of bone tissue is called osteoid, which is the organic part before mineralization.

Water Content in Bone Matrix

• Approximately 25% of the bone matrix is composed of water, essential for maintaining the structure and function.

Location of Osteocytes

• Osteocytes are embedded within the lacunae of bone, surrounded by the mineralized matrix.

Function of Osteoclasts

• The main function of osteoclasts is to resorb bone tissue, facilitating the breakdown of bone during remodeling.

Mesoderm-Derived Cells

• Osteoblasts, osteoclasts, and osteocytes are derived from mesoderm, highlighting their embryonic origin in skeletal development.
