Brush border is the peculiarity of

Options

A. syncytial cells
B. nerve cells
C. absorptive cells
D. blood cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Brush Border":**
- The term "brush border" refers to a specific structure found on the surface of certain epithelial cells. It is characterized by the presence of numerous tiny, finger-like projections.

2. **Identifying the Projections:**
- These finger-like projections are known as microvilli. They extend from the plasma membrane of the cells and serve to increase the surface area.

3. **Function of Microvilli:**
- The primary function of microvilli is to enhance the surface area available for absorption. This is particularly important in cells that are involved in the absorption of nutrients.

4. **Examples of Cells with Brush Border:**
- A key example of cells with a brush border is found in the small intestine, particularly in the duodenum. The epithelial cells lining the duodenum have microvilli that facilitate the absorption of digested nutrients.

5. **Eliminating Incorrect Options:**
- Syncytial cells are multinucleated and do not have a role in absorption.
- Nerve cells are specialized for signal transmission and do not possess a brush border.
- Blood cells primarily function in the transport of gases and are not involved in absorption.

6. **Conclusion:**
- Based on the characteristics and functions discussed, the brush border is a peculiarity of absorptive cells.

**Final Answer:**
- The brush border is the peculiarity of absorptive cells.
