Which of the following tissue is also called urothelium ?

Options

A. Transitional epithelium
B. Non-keratinized epithelium
C. Keratinized epithelium
D. Epithelium of nephron

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which tissue is referred to as "urothelium."

2. **Identifying the Options**: The options given are:
- Transitional epithelium
- Non-keratinized epithelium
- Keratinized epithelium
- Epithelium of nephron

3. **Analyzing Each Option**:
- **Transitional Epithelium**: This type of epithelium is specifically designed to stretch and is found in the urinary bladder. It allows for the expansion of the bladder as it fills with urine, which is why it is also called urothelium.
- **Non-Keratinized Epithelium**: This type of epithelium is found in areas such as the oral cavity and esophagus. It does not relate to the urinary system.
- **Keratinized Epithelium**: This type is found in the skin, particularly in areas like the palms and soles. It also does not relate to the urinary system.
- **Epithelium of Nephron**: The nephron is the functional unit of the kidney, and its epithelium includes specialized cells like podocytes, but it is not referred to as urothelium.

4. **Conclusion**: After analyzing the options, it is clear that the correct answer is **Transitional Epithelium**, as it is the tissue that lines the urinary bladder and is also known as urothelium.

**Final Answer**: Transitional epithelium is also called urothelium.
