which of the following set includes the correct location of different parts of cortical nephron inside kidney?

Options

A. cortex (malpighiam corpuscles), cortex (PCT), medula (DCT), medula ( loop of Henie)
B. cortex (malpighiam corpuscles), medula (PCT), medula (DCT), medula (loop of Henie)
C. medula (Malpighiam corpuscles), medula (PCT), cortex(DCT), cortex (loop of Henie)
D. cortex (Malpighiam corpuscles), cortex (PCT), cortex (DCT), medula (loop of Henie)

Answer

To determine the correct location of different parts of the cortical nephron inside the kidney, we need to analyze the options provided and understand the anatomy of the nephron.

### Step-by-Step Solution:

1. **Understand the Structure of the Cortical Nephron**:
- The cortical nephron consists of several key components: the Malpighian corpuscle (Bowman's capsule and glomerulus), proximal convoluted tubule (PCT), distal convoluted tubule (DCT), and the loop of Henle.
- The Malpighian corpuscle, PCT, and DCT are located in the cortex of the kidney, while the loop of Henle extends into the medulla.

2. **Analyze Each Option**:
- **Option A**: Cortex (Malpighian corpuscles), Cortex (PCT), Medulla (DCT), Medulla (loop of Henle).
- Malpighian corpuscles and PCT are correctly located in the cortex, but DCT should also be in the cortex, making this option incorrect.

- **Option B**: Cortex (Malpighian corpuscles), Medulla (PCT), Medulla (DCT), Medulla (loop of Henle).
- Here, both PCT and DCT are incorrectly placed in the medulla. This option is incorrect.

- **Option C**: Medulla (Malpighian corpuscles), Medulla (PCT), Cortex (DCT), Cortex (loop of Henle).
- This option incorrectly places the Malpighian corpuscles and PCT in the medulla. This option is incorrect.

- **Option D**: Cortex (Malpighian corpuscles), Cortex (PCT), Cortex (DCT), Medulla (loop of Henle).
- This option correctly places the Malpighian corpuscles, PCT, and DCT in the cortex, and the loop of Henle in the medulla. This option is correct.

3. **Conclusion**:
- The correct answer is **Option D**: Cortex (Malpighian corpuscles), Cortex (PCT), Cortex (DCT), Medulla (loop of Henle).
