Schneiderian epithelium is found in

Options

A. nasal passage
B. trachea
C. retina
D. Bowman's capsule

Answer

**Step-by-Step Solution:**

1. **Identify the Epithelium in Question**: The question asks about Schneiderian epithelium. It is important to recognize what this type of epithelium is and where it is typically found.

2. **Analyze the Options Provided**: The options given are:
- Nasal passage
- Trachea
- Retina
- Bowman's cartilage

3. **Recall the Function and Location of Schneiderian Epithelium**: Schneiderian epithelium is a type of respiratory epithelium that is primarily found in the nasal passages. It is specialized for the functions of olfaction (sense of smell) and air filtration.

4. **Describe the Composition of Schneiderian Epithelium**: This epithelium consists of three types of cells:
- **Basal Cells**: These cells serve as stem cells for regeneration.
- **Supporting Cells**: These cells provide structural support and help maintain the integrity of the epithelium.
- **Neurosecretory Cells**: These cells are involved in the secretion of substances that can influence the function of other cells.

5. **Select the Correct Answer**: Based on the information gathered, the correct answer to the question is that Schneiderian epithelium is found in the **nasal passage**.

**Final Answer**: Schneiderian epithelium is found in the nasal passage.
