The cells which line the neck and the body of the nephron are

Options

A. Smooth squamous epithelial
B. Tesselated epithelial
C. Stratified epithelial
D. Cuboidal and ciliated epithelial

Answer

To answer the question about the cells that line the neck and body of the nephron, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Nephron**:
- The nephron is the basic structural and functional unit of the kidney. It plays a crucial role in filtering blood and forming urine.

2. **Identifying the Parts of the Nephron**:
- The nephron consists of several parts, including the renal corpuscle (Bowman's capsule and glomerulus) and the renal tubule (which includes the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct).
- The neck and body of the nephron refer primarily to the parts of the renal tubule.

3. **Examining the Options**:
- The question provides four options for the type of cells lining the neck and body of the nephron:
- A) Smooth squamous epithelial
- B) Tessellated epithelial
- C) Stratified epithelial
- D) Cuboidal and ciliated epithelial

4. **Analyzing Each Option**:
- **Option A: Smooth Squamous Epithelial**:
- This type of epithelium is found in areas where diffusion occurs, such as in the alveoli of the lungs and lining of blood vessels. It is not found in the nephron.
- **Option B: Tessellated Epithelial**:
- This is another term for smooth squamous epithelium, so it is also incorrect for the nephron.
- **Option C: Stratified Epithelial**:
- Stratified epithelium consists of multiple layers and is found in areas subject to abrasion (like the skin and esophagus). It is not present in the nephron.
- **Option D: Cuboidal and Ciliated Epithelial**:
- This type of epithelium is characterized by cube-shaped cells and may have microvilli (not cilia) on their surface, which increases surface area for absorption. This is the correct type of epithelium found in the neck and body of the nephron.

5. **Conclusion**:
- The correct answer is **D) Cuboidal and ciliated epithelial**, as these cells line the neck and body of the nephron, facilitating the processes of filtration and reabsorption.
