What is the diaphysis of a bone?

Back

The diaphysis is the long, tubular shaft of a bone, primarily composed of compact bone and containing the medullary cavity.

Front

What is a comminuted fracture?

Back

A comminuted fracture is a type of bone fracture where the bone is broken into multiple fragments.

Front

What characterizes an open or compound fracture?

Back

An open or compound fracture occurs when the broken bone penetrates through the skin.

Front

What is the proximal epiphysis?

Back

The proximal epiphysis is the end part of a long bone that is closest to the body's center, often involved in joint formation.

Front

What is NOT a step in the repair process of a simple fracture?

Back

Scab formation is NOT a step in the repair process of a simple fracture.

Front

What is the role of hematoma formation in fracture healing?

Back

Hematoma formation is the first step in fracture healing, where blood collects at the fracture site, providing a scaffold for healing.

Front

What is the function of fibrocartilage callus in fracture repair?

Back

The fibrocartilage callus forms a temporary bridge between the broken bone ends, aiding in stabilization during healing.

Front

What is bone remodeling?

Back

Bone remodeling is the process where old bone tissue is replaced by new bone tissue, ensuring the bone maintains its strength and integrity.

Front

What are the two main types of bone fractures?

Back

The two main types of bone fractures are closed (simple) fractures, where the skin remains intact, and open (compound) fractures, where the bone breaks through the skin.

Front

What is the difference between a simple fracture and a compound fracture?

Back

A simple fracture does not break the skin, while a compound fracture does, exposing the bone to the external environment.
