Answer

To determine what standing on tiptoe is an example of, we can analyze the movements involved in this action step by step.

### Step-by-Step Solution:

1. **Understanding Joint Movements**:
- In human anatomy, joints can perform various movements such as flexion, extension, elevation, and retraction. It is important to know what each of these movements entails.

2. **Defining Flexion and Extension**:
- **Flexion**: This is the bending movement that decreases the angle between two body parts. For example, bending the elbow or knee.
- **Extension**: This is the straightening movement that increases the angle between body parts. For example, straightening the elbow or knee.

3. **Analyzing the Action of Standing on Tiptoe**:
- When you stand on your tiptoes, you are primarily using your ankle joint. In this position, the heel is lifted off the ground, and the toes are pointed downwards.
- This action involves straightening the ankle joint, which increases the angle between the foot and the leg.

4. **Identifying the Correct Movement**:
- Since standing on tiptoe involves straightening the ankle joint, this action is classified as **extension** of the ankle joint.

5. **Conclusion**:
- Therefore, standing on tiptoe is an example of **extension**.

### Final Answer:
Standing on tiptoe is an example of **extension**.
