The epithelia present in prostatic urethra and penile urethra respectively 

Options

A. Pseudostratified non ciliated columnar epithelium and transitional epithelium
B. Transitional epithelium and pseudostratified non ciliated columnar epithelium
C. Transitional epithelium and stratified non keratinised squamous epithelium
D. Stratified non-keratinised squamous epithelium and
pseudostratified non-ciliated columnar epithelium

Answer

To determine the types of epithelia present in the prostatic urethra and penile urethra, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Urethra Sections**:
- The urethra is divided into different sections: prostatic urethra, membranous urethra, and penile urethra. We need to focus on the prostatic and penile urethra.

2. **Understand the Epithelial Types**:
- Epithelial tissues can be classified based on their shape and layering. The main types relevant here are:
- Transitional epithelium
- Stratified non-keratinized squamous epithelium
- Pseudostratified non-ciliated columnar epithelium
- Stratified columnar epithelium

3. **Epithelial Lining of Prostatic Urethra**:
- The prostatic urethra is lined with transitional epithelium (urothelium). This type of epithelium is specialized for stretching and is found in areas that need to accommodate fluctuating volumes of liquid, such as the bladder and parts of the urethra.

4. **Epithelial Lining of Penile Urethra**:
- The penile urethra (also known as the spongy urethra) is lined with pseudostratified non-ciliated columnar epithelium. This epithelium is characterized by its columnar cells that appear to be layered but are actually a single layer with varying cell heights.

5. **Match the Options**:
- Now, we need to match these findings with the provided options:
- **Option 1**: Stratified non-ciliated columnar epithelium and transitional epithelium (Incorrect)
- **Option 2**: Transitional epithelium and stratified non-ciliated columnar epithelium (Incorrect)
- **Option 3**: Transitional epithelium and stratified non-keratinized squamous epithelium (Incorrect)
- **Option 4**: Stratified non-keratinized squamous epithelium and pseudostratified non-ciliated columnar epithelium (Incorrect)
- **Correct Answer**: Transitional epithelium (prostatic urethra) and pseudostratified non-ciliated columnar epithelium (penile urethra).

6. **Final Conclusion**:
- The correct answer is that the prostatic urethra is lined with transitional epithelium, and the penile urethra is lined with pseudostratified non-ciliated columnar epithelium.
