Answer
Osteoblasts add bone matrix to the outside of the diaphysis during appositional growth.
Solution
1. In appositional growth, bones widen by adding new bone tissue at the surface of the diaphysis.
2. The cells responsible for forming new bone matrix are known as \( \textbf{osteoblasts} \).
3. Osteoblasts secrete osteoid, which later mineralizes to become mature bone.
4. Therefore, the correct answer is:
**B) Osteoblasts**.

When growing bones widen through appositional growth, osteoblasts are the star players! These fabulous bone-building cells add new bone matrix to the outer layer of the diaphysis, making your bones stronger and thicker. So, think of them as the construction workers who create the framework for your bone structure! Now, let’s talk about how this all happens. As osteoblasts work their magic, they deposit new bone material, and once embedded in the matrix, some of them become osteocytes, which keep an eye on the bone health and communicate with other bone cells. It’s a whole collaborative effort to keep your bones robust!
