MICROANATOMY

Detailed explanation-1: -Appositional growth is the process by which old bone that lines the medullary cavity is reabsorbed and new bone tissue is grown beneath the periosteum, increasing bone diameter.

Detailed explanation-2: -Even though bones stop growing in length in early adulthood, they can continue to increase in thickness or diameter throughout life in response to stress from increased muscle activity or to weight. The increase in diameter is called appositional growth.

Detailed explanation-3: -While bones are increasing in length, they are also increasing in diameter; growth in diameter can continue even after longitudinal growth ceases. This growth by adding to the free surface of bone is called appositional growth.

Detailed explanation-4: -Bone growth is either longitudinal or appositional. Longitudinal bone growth is the ossification of the bone that grows lengthwise until they stop growing. Appositional bone growth continues till death and is the growth of the bones in diameter or thickness.
