Locate the osteons (the structural units of bone), the Haversian canals (central channels for blood vessels), and the osteocytes (bone cells). Biology, 8th Grade (Kolesov, Mash, Belyaev) Topic: Studying

Although not directly visible under the microscope, the textbook notes that organic substances (collagen) give bones flexibility , while inorganic salts (calcium and phosphorus) provide hardness . 6. Conclusion Although not directly visible under the microscope, the

To study the structural features of bone tissue using a microscope, identify the relationship between the structure of bone cells and their functions, and understand the organic and inorganic composition of bones. 2. Equipment and Materials Compound light microscope. Permanent slide of "Bone Tissue" (transverse section).

Draw a diagram of what is observed under the microscope and label the main parts. 4. Results (Observations)

The network of osteocyte processes allows cells deep within the hard matrix to receive oxygen and nutrients from the central canal.
