Questions: Bone growth in which the bone increases in diameter is called

The answer is the third one: appositional growth.

Explanation for each option:

1. Cancellous bone growth: This term refers to the growth of spongy bone, which is not specifically about increasing the diameter of a bone. Therefore, this is incorrect.

2. Interstitial growth: This type of growth occurs within the interior of tissues, such as cartilage, and is responsible for lengthening rather than increasing diameter. Thus, this is incorrect.

3. Appositional growth: This is the process by which bones increase in diameter. It involves the addition of new layers on the surface of existing bone, making it the correct answer.

4. Epiphyseal growth: This refers to the growth at the epiphyseal plate (growth plate) which contributes to the lengthening of long bones, not the increase in diameter. Therefore, this is incorrect.

5. Endosteal growth: This involves the growth of bone tissue on the inner surface, which can contribute to the remodeling of bone but is not specifically about increasing the diameter. Thus, this is incorrect.

In summary, appositional growth is the correct term for the process by which bones increase in diameter.
