Choose the part of the uriniferous table that shows the presence of cuboidal epithelium with brush border?

Options

A. Proximal convoluted tubule
B. Distal convoluted tubule
C. Bowman's capsule
D. Glomerulus

Answer

To solve the question regarding which part of the uriniferous tubule shows the presence of cuboidal epithelium with a brush border, we can follow these steps:

### Step 1: Understand the Structure of the Nephron
The nephron is the functional unit of the kidney and consists of several parts, including:
- Bowman's capsule
- Proximal convoluted tubule (PCT)
- Loop of Henle
- Distal convoluted tubule (DCT)
- Collecting duct

### Step 2: Identify the Epithelium Types
Each part of the nephron has a specific type of epithelial lining:
- **Bowman's capsule**: Simple squamous epithelium
- **Proximal convoluted tubule (PCT)**: Simple cuboidal epithelium with a brush border
- **Loop of Henle**: Simple squamous epithelium
- **Distal convoluted tubule (DCT)**: Simple cuboidal epithelium (without a brush border)
- **Collecting duct**: Cuboidal to columnar epithelium (varies)

### Step 3: Focus on the Proximal Convoluted Tubule
The proximal convoluted tubule (PCT) is specifically lined with simple cuboidal epithelium that has microvilli (brush border). This structure increases the surface area for absorption.

### Step 4: Conclusion
From the analysis, the part of the uriniferous tubule that shows the presence of cuboidal epithelium with a brush border is the **Proximal Convoluted Tubule (PCT)**.

### Final Answer
**Proximal Convoluted Tubule (PCT)**
