Spongy bone + red marrow. • Metaphysis is the area between the epiphysis and diaphysis and includes the epiphyseal plate in growing bones. • Articular cartilage (hyaline) over joint surfaces acts as friction reducer & shock absorber. • Periosteum and endosteum. © Copyright Universidad Europea.

It contains only one layer of osteogenic cells and a small amount of connective tissue. Periosteum: membrane covering bones (except articular surface): – Fibrous layer (external): dense irregular connective tissue. – Osteogenic layer (internal): osteogenic cells (width) and blood vessels. © Copyright Universidad Europea.
