Bone Structure and Classification

The video tutorial covers the microscopic anatomy of bones, focusing on compact bones. It explains how bones are classified by shape, including long, round, irregular, short, and flat bones. The tutorial also details the structure of a typical long bone, highlighting parts like the diaphysis and epiphysis. Additionally, it discusses bone composition, including spongy and compact bone, and the role of marrow. The growth process of bones, including the epiphyseal line and growth plate, is also covered.
