The main shaft-like portion of a long bone is called:

• Epiphysis

• Metaphysis

• Diaphysis

• Endosteum

The outer fibrous covering of bone is known as:

• Endosteum

• Periosteum

• Epiphysis

• Trabeculae

The hollow tube-like structure within the diaphysis is the:

• Medullary cavity

• Epiphyseal plate

• Metaphysis

• Cortex

The inner lining of the medullary cavity is the:

• Trabeculae

• Endosteum

• Periosteum

• Epiphysis

The microscopic structural unit of compact bone is called:

• Trabecula

• Haversian system

• Osteoid

• Epiphyseal plate

The web-like arrangement in cancellous bone is formed by:

• Osteons

• Trabeculae

• Epiphyses

• Osteoids

Bone formation is termed:

• Resorption

• Ossification

• Calcification

• Apposition

The cartilage plate separating the epiphysis and diaphysis during growth is:

• Articular cartilage

• Epiphyseal cartilage

The flared area where the diaphysis meets the epiphyseal plate is:

• Endosteum

• Metaphysis

• Compact bone

• Trabeculae

Cells that build new bone are called:

• Osteoclasts

• Osteoblasts

• Chondrocytes

• Osteocytes
