Pseudostratified epithelium is found in :

Options

A. rectum
B. urinary bladder
C. wall of oesophagus
D. inner liming of bronchiole

Answer

**Step-by-Step Solution:**

1. **Understanding Pseudostratified Epithelium:**
- Pseudostratified epithelium is a type of epithelial tissue that appears to be stratified (layered) but is actually a single layer of cells with varying heights. This type of epithelium often contains cilia.

2. **Analyzing the Options:**
- The question provides four options where pseudostratified epithelium might be found. We need to evaluate each option to determine if it contains pseudostratified epithelium.

3. **Option 1: Rectum**
- The rectum is lined with non-keratinized squamous epithelium, which is not pseudostratified. Therefore, this option is incorrect.

4. **Option 2: Urinary Bladder**
- The urinary bladder is lined with transitional epithelium, which allows it to stretch. This is also not pseudostratified epithelium. Thus, this option is incorrect.

5. **Option 3: Wall of Oesophagus**
- The wall of the oesophagus is lined with non-keratinized squamous epithelium, similar to the rectum. Therefore, this option is incorrect as well.

6. **Option 4: Inner Lining of Bronchioles**
- The inner lining of bronchioles is lined with pseudostratified ciliated columnar epithelium, which is characteristic of the respiratory system. This option is correct.

7. **Conclusion:**
- Based on the analysis, the correct answer is that pseudostratified epithelium is found in the inner lining of bronchioles.

**Final Answer:**
Pseudostratified epithelium is found in the inner lining of bronchioles.
