Epithelium present in cornea , oesophagus , urethra and vagina is

Options

A. Glandular
B. Ciliated
C. Stratified columnar
D. Stratified squamous .

Answer

To determine the type of epithelium present in the cornea, oesophagus, urethra, and vagina, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Locations**:
- The cornea is the transparent front part of the eye.
- The oesophagus is the tube that connects the throat to the stomach.
- The urethra is the duct through which urine is discharged from the bladder.
- The vagina is the muscular tube leading from the external genitals to the cervix of the uterus.

2. **Understand the Function of Each Location**:
- The cornea needs to be protective and allow light to pass through.
- The oesophagus requires a protective lining against abrasion from food.
- The urethra needs to be protective as it carries urine.
- The vagina also requires protection and flexibility.

3. **Consider the Types of Epithelium**:
- Glandular epithelium: Specialized for secretion, found in glands.
- Ciliated epithelium: Contains cilia, found in respiratory tract and reproductive organs.
- Stratified columnar epithelium: Rare, found in specific areas like the pharynx and male urethra.
- Stratified squamous epithelium: Multiple layers of cells, providing protection against abrasion.

4. **Match the Function with the Epithelium Type**:
- Given the need for protection in all four locations (cornea, oesophagus, urethra, vagina), stratified squamous epithelium is most suitable as it provides a thick protective layer.

5. **Conclusion**:
- The correct type of epithelium present in the cornea, oesophagus, urethra, and vagina is **stratified squamous epithelium**.
