Bone formed by ossification of tendon is 

Options

A. Sesamoid
B. Cartilage or repliacing bone
C. Investing or dermal bone
D. Membranous bone

Answer

**Step-by-Step Solution:**

1. **Understanding Tendons**:
- Tendons are strong, fibrous cords made of collagen that connect muscles to bones. They are flexible but not elastic, meaning they can withstand tension but do not stretch significantly.

2. **Ossification Process**:
- Ossification is the process through which bone is formed. In some cases, this process can occur within tendons, leading to the formation of bone tissue.

3. **Identifying the Type of Bone**:
- The type of bone that forms through the ossification of tendons is known as a sesamoid bone.

4. **Function of Sesamoid Bones**:
- Sesamoid bones serve several functions, including modifying pressure, reducing friction, and improving the mechanical advantage of muscles. They are typically found in locations where tendons pass over joints.

5. **Conclusion**:
- Therefore, the bone formed by the ossification of tendon is called a **sesamoid bone**.
