Which one is formed by the ossifaication of tendon?

Options

A. Tibia
B. patella
C. Trapezoid
D. Calcaneum

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which structure is formed by the ossification of a tendon. Ossification refers to the process of bone formation.

2. **Identifying the Correct Answer**: The correct answer is the sesamoid bone. Sesamoid bones are formed from the ossification of tendons.

3. **Characteristics of Sesamoid Bones**: Sesamoid bones are typically small and round in shape. They are embedded within tendons and help to protect the tendon from stress and wear and tear.

4. **Examples of Sesamoid Bones**: A well-known example of a sesamoid bone is the patella, commonly known as the kneecap. The patella protects the knee joint and aids in the function of the knee.

5. **Eliminating Incorrect Options**:
- Tibia: This is a long bone (shin bone) and not formed from tendon ossification.
- Trapezoid: This is a carpal bone located in the wrist and is not a sesamoid bone.
- Calcaneum: This is the heel bone and also not formed from tendon ossification.

6. **Final Answer**: Therefore, the answer to the question is the patella, which is a sesamoid bone formed by the ossification of a tendon.
