Solution

The correct statement about bone remodeling and repair is: "Exposure of a bone to increased stress can lead to bone remodeling."

Here's why:

  1. Bone remodeling involves removal of old bone by osteoclasts, not osteoblasts. Osteoblasts are responsible for bone formation.

  2. As a long bone increases in diameter, the size of the marrow cavity actually increases, not decreases. This is due to the activity of osteoclasts, which break down bone tissue.

  3. Exposure of a bone to increased stress can indeed lead to bone remodeling. This is because the bone adapts to withstand the stress, leading to changes in its structure.

  4. Bone remodeling does involve the activity of osteoclasts and osteoblasts. Osteoclasts break down old bone tissue, and osteoblasts form new bone tissue.

Therefore, not all of the choices are correct.
