Cartilaginous joints

Options

A. Permit slight movements
B. Are found in symphysis
C. Are found in the bodies of vertebrae
D. All the above.

Answer

**Step-by-Step Text Solution:**

1. **Definition of Cartilaginous Joints:**
- Cartilaginous joints are types of joints where two bones are connected by cartilage. This cartilage can be either hyaline cartilage or fibrocartilage.

2. **Characteristics of Cartilaginous Joints:**
- These joints do not have a joint cavity, which differentiates them from synovial joints.
- They allow for slight movements between the bones.

3. **Types of Cartilaginous Joints:**
- There are two main types of cartilaginous joints:
- **Synchondrosis:** In these joints, the bones are joined by hyaline cartilage. An example is the joint between the first rib and the manubrium of the sternum.
- **Symphysis:** In these joints, the bones are joined by fibrocartilage. An example is the intervertebral discs found between the vertebrae.

4. **Examples of Cartilaginous Joints:**
- The joint between the manubrium and the sternum is a synchondrosis joint.
- The intervertebral discs and the pubic symphysis are examples of symphysis joints.

5. **Conclusion:**
- Given the characteristics and examples discussed, the correct answer to the question regarding cartilaginous joints is "all of the above," as all statements about their properties and examples are true.
