What is appositional bone growth?
Understand the Problem
The question is asking for an explanation of appositional bone growth, which refers to the process by which bones increase in diameter or thickness. This type of growth occurs as new bone tissue is added to the outer surface of existing bone, while old bone tissue is resorbed from the inner surface. Generally, it takes place under the influence of stress and mechanical load, leading to the strengthening of bones.
Answer
Appositional growth is the increase in bone diameter by adding new bone tissue on the bone's surface.
Appositional growth refers to the increase in the diameter of bones by the addition of new bone tissue on the surface of existing bones. This process involves osteoblasts secreting bone matrix on the surface and osteoclasts breaking down bone on the inner surface.

More Information
Appositional bone growth is crucial for the supporting capacity and thickness of bones, providing structural integrity as they grow.
Tips
A common mistake is to confuse appositional growth with interstitial growth, which increases the length of bones rather than the diameter. They are distinct processes.
