Interarticular disc occurs in
(a) Wall of heart
(b) Wall of liver
(c) Pubic symphysis
(d) In between two vertebrae

Options

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

Answer

To solve the question about where interarticular discs occur, we will analyze each option step by step.

### Step 1: Understand what an interarticular disc is
An interarticular disc is a thin, oval plate made of fibrous cartilage. It is important in the context of joints and movement.

**Hint:** Remember that interarticular discs are made of fibrous cartilage and are involved in joint function.

### Step 2: Analyze each option
- **Option (a): Wall of heart**
- The wall of the heart is primarily made up of cardiac muscle and does not contain interarticular discs. Therefore, this option is incorrect.

- **Option (b): Wall of liver**
- The liver is composed of hepatocytes and connective tissue, but it does not have interarticular discs. Hence, this option is also incorrect.

- **Option (c): Pubic symphysis**
- The pubic symphysis is a joint that connects the left and right pubic bones. It does contain a fibrocartilaginous structure, but it is not typically referred to as an interarticular disc. Thus, this option is not the best fit.

- **Option (d): In between two vertebrae**
- Interarticular discs are indeed found between the vertebrae in the vertebral column. They play a crucial role in providing support and allowing movement between the vertebrae. Therefore, this option is correct.

### Step 3: Conclusion
Based on the analysis, the correct answer is **(d) In between two vertebrae**.

**Final Answer:** (d) In between two vertebrae
