Bone Fracture and Repair

Front

What is the role of mechanical stress in bone remodeling?

Back

Mechanical stress helps replace spongy bone with compact bone during the remodeling phase.

Front

What replaces the fibrocartilage callus during fracture repair?

Back

The fibrocartilage callus is replaced with spongy bone.

Front

What is a greenstick fracture?

Back

A greenstick fracture is an incomplete fracture usually seen in children.

Front

What are bone-forming cells called?

Back

Bone-forming cells are called osteoblasts.

Front

What cells are responsible for constructing a hard callus during fracture repair?

Back

Osteoblasts are responsible for constructing a hard callus.

Front

What is the function of osteoclasts?

Back

Osteoclasts are responsible for bone resorption, breaking down bone tissue.

Front

What is the difference between compact bone and spongy bone?

Back

Compact bone is dense and forms the outer layer of bones, while spongy bone is lighter, less dense, and found inside bones.

Front

What is the process of bone healing called?

Back

The process of bone healing is called bone repair.

Front

What is a pathological fracture?

Back

A pathological fracture is a break in a bone that occurs due to disease or weakness in the bone structure.

Front

What is the first step in the bone healing process?

Back

The first step in the bone healing process is the formation of a hematoma at the fracture site.
