Questions: Bones grow in diameter by interstitial growth.

The answer is False.

Explanation: Bones grow in diameter through a process called appositional growth, not interstitial growth. Interstitial growth refers to the growth that occurs within the interior of a structure, such as the lengthening of bones at the epiphyseal plates (growth plates) during childhood and adolescence. Appositional growth, on the other hand, involves the addition of new layers to the outer surface of the bone, which increases its diameter. This process is carried out by osteoblasts in the periosteum, the connective tissue surrounding the bone.
