Our knee and elbow joints are gliding points.

Answer

**Step-by-Step Solution:**

1. **Understanding Joint Types**: First, we need to understand what gliding joints are. Gliding joints are joints where two flat bone surfaces slide over one another. This allows for a range of movements in various directions.

2. **Identifying Knee and Elbow Joints**: Next, we identify the knee and elbow joints. These joints are often mistakenly referred to as gliding joints.

3. **Correct Classification**: Upon closer examination, we find that the knee and elbow joints do not allow for the sliding movement characteristic of gliding joints. Instead, they allow for movement in one direction, similar to how a door hinge operates.

4. **Defining Hinge Joints**: The knee and elbow joints are classified as hinge joints. Hinge joints permit movement in one plane, allowing for bending and straightening, much like a door that opens and closes.

5. **Conclusion**: Therefore, the statement that "knee and elbow joints are gliding joints" is false. They are actually hinge joints.

**Final Answer**: The statement is false; the knee and elbow joints are hinge joints, not gliding joints.
