Vasa efferentia possess

Options

A. Peristalasis
B. Secretory cells
C. Ciliated c ells
D. Openings for seminal vesicles.

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure**: Vasa efferentia are small ducts that connect the rete testis to the epididymis in the male reproductive system. They play a crucial role in transporting sperm.

2. **Function of Vasa Efferentia**: The primary function of vasa efferentia is to carry sperm from the rete testis to the epididymis, where sperm maturation occurs.

3. **Histological Features**: The walls of vasa efferentia are lined with ciliated epithelium. This ciliated structure helps in the movement of sperm through the ducts.

4. **Analyzing the Options**:
- **A. Peristalsis**: This refers to the wave-like muscle contractions that move food through the digestive tract, not a feature of vasa efferentia.
- **B. Secretory cells**: While secretory cells are present in various parts of the reproductive system, they are not a defining feature of vasa efferentia.
- **C. Ciliated C-cells**: This option is correct as the ciliated epithelium helps in the movement of sperm.
- **D. Opening for seminal vesicles**: This is not related to vasa efferentia, as seminal vesicles are separate structures.

5. **Conclusion**: Based on the analysis, vasa efferentia possess ciliated C-cells, making the correct answer option C.

**Final Answer**: C. Ciliated C-cells
