What determines the strength and lightness of bones?

Nutrients and oxygen reach osteocytes through tiny canals called canaliculi, which connect the cells to the blood vessels in the Haversian canal. IV. Conclusion

Strength is provided by the inorganic mineral salts (calcium and phosphorus), while the organic fibers (collagen) provide flexibility. The tubular structure of osteons ensures maximum strength with minimum weight.

Identify the mature bone cells located between the concentric rings. They often appear as dark, "spider-like" spots with small processes. What determines the strength and lightness of bones

How do bone cells receive nutrients if the matrix is solid?

The microscopic study of bone tissue reveals a highly organized structure called the . This arrangement allows bone to act as a supportive framework for the body while remaining metabolically active and capable of growth and repair.
