Inter-articular disc occurs in

Options

A. Wall of heart
B. Wall of liver
C. Public symphysis
D. In between two vertebrae.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks where inter-articular discs occur. We have four options: wall of the heart, wall of the liver, pubic symphysis, and in between the two vertebrae.

2. **Analyzing the Options**:
- **Wall of the Heart**: Inter-articular discs are not found here; this option is incorrect.
- **Wall of the Liver**: Similarly, inter-articular discs are not present in the liver; this option is also incorrect.
- **Pubic Symphysis**: This is a joint between the two pubic bones, but it does not specifically refer to inter-articular discs.
- **In Between the Two Vertebrae**: Inter-articular discs are indeed found between vertebrae, where they serve as fibrous cartilage joints.

3. **Identifying the Correct Answer**: After analyzing the options, the correct answer is that inter-articular discs occur in between the two vertebrae.

4. **Explanation of the Function**: Inter-articular discs are made of fibrous cartilage and are thin and oval in shape. They allow slight movements between the vertebrae, contributing to the flexibility of the spinal column.

5. **Final Conclusion**: Therefore, the correct option is "in between the two vertebrae."
