Which of the following is a cartilaginous joint?

Options

A. Suture
B. Elbow joint
C. Synovial joint
D. Pubic symphysis

Answer

To determine which of the following is a cartilaginous joint, we need to analyze each option provided:

1. **Suture**: This is a type of fibrous joint found between the bones of the skull. Sutures are immovable joints, meaning they do not allow any movement. Therefore, this is not a cartilaginous joint.

2. **Elbow Joint**: The elbow is classified as a synovial joint, which is a type of freely movable joint. Synovial joints allow for a wide range of motion in various directions. Hence, this is not a cartilaginous joint.

3. **Synovial Joint**: This term refers to a category of joints that are characterized by a fluid-filled joint cavity, allowing for significant movement. Since this is a broader category that includes joints like the elbow, it is not a cartilaginous joint.

4. **Pubic Symphysis**: This joint is located between the pubic bones of the pelvis. It is classified as a cartilaginous joint because it is made of cartilage and allows for slight movement. This joint is an example of a slightly movable joint, making it the correct answer.

**Conclusion**: The correct answer to the question "Which of the following is a cartilaginous joint?" is the **pubic symphysis**.
