Which of the following macrophages is found in brain ?

Options

A. Histiocytes
B. Messangial cells
C. Microglial cells
D. Kupffer cells

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which type of macrophage is found in the brain. Macrophages are immune cells that play a crucial role in the body's defense mechanism.

2. **Analyzing the Options**:
- **Option 1: Histiocytes** - These are immune cells found in various organs, including bone marrow, skin, lungs, and lymphatic tissues. They are not specific to the brain.
- **Option 2: Mesenchymal Cells** - These are specialized cells found primarily in the kidneys, particularly in the glomerulus. They provide phagocytic protection but are not found in the brain.
- **Option 3: Microglial Cells** - These are specialized macrophages located in the central nervous system (CNS), including the brain. They serve as the primary immune defense in the brain, protecting it from pathogens.
- **Option 4: Kupffer Cells** - These are macrophages found in the liver. They are involved in filtering blood and are not present in the brain.

3. **Identifying the Correct Answer**: Based on the analysis, the macrophages that are specifically found in the brain are the **Microglial Cells**.

4. **Conclusion**: Therefore, the correct answer to the question is **Microglial Cells**.
