Observe the concentric layers (lamellae) of mineralized matrix surrounding the central canal.

Permanent slide of "Bone Tissue" (transverse or longitudinal section). Textbook and instructional diagrams. II. Procedure & Observations

Place the slide under the microscope. At low magnification (10x), identify the general pattern of the bone section. Structural Identification:

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

What determines the strength and lightness of bones?

Based on common 8th-grade biology curricula (such as those by , Kolesov , or Dragomilov ), Laboratory Work No. 3 typically focuses on the Microscopic Structure of Bone Tissue or Human Reflexes .
