In cortex area of kidney all structure are found except `:-`

Options

A. Bowman capsule
B. D.C.T.
C. Rays
D. Malphighian body

Answer

To solve the question regarding which structures are found in the cortex area of the kidney, we need to analyze the components of the nephron and their locations within the kidney.

### Step-by-Step Solution:

1. **Understanding Kidney Structure**:
- The kidney is divided into two main regions: the outer region called the **cortex** and the inner region known as the **medulla**.

2. **Identifying Nephron Components**:
- The nephron, the functional unit of the kidney, consists of several parts:
- **Bowman's capsule**: A cup-shaped structure that encloses the glomerulus.
- **Proximal Convoluted Tubule (PCT)**: The first segment of the renal tubule.
- **Loop of Henle (LOH)**: A U-shaped segment that extends into the medulla.
- **Distal Convoluted Tubule (DCT)**: The segment following the loop of Henle.
- **Collecting Duct**: The final part of the nephron that collects urine from multiple nephrons.

3. **Locating Each Structure**:
- **Bowman's capsule** is located in the cortex.
- **PCT** is also located in the cortex.
- **DCT** is found in the cortex.
- **Loop of Henle** extends into the medulla, which means it is not located in the cortex.

4. **Analyzing the Options**:
- The question asks for the structure that is **not** found in the cortex. The options include:
- Bowman's capsule
- DCT
- Malpighian body (which includes Bowman's capsule and glomerulus)
- Medullary rays

5. **Conclusion**:
- Since the **Loop of Henle** is the only structure that extends into the medulla and is not found in the cortex, the correct answer to the question is **medullary rays**.

### Final Answer:
The structure that is not found in the cortex area of the kidney is **medullary rays**.
