Seminiferous tubules are composed of

Options

A. Spermatogonia
B. Glandular epithelium
C. Sensory epithelium
D. Germinal epithelium

Answer

**Step-by-Step Solution:**

1. **Identify the Structure**: The question asks about the composition of seminiferous tubules, which are found in the testes, the male reproductive organs.

2. **Understand the Function**: Seminiferous tubules are crucial for the process of spermatogenesis, where sperm cells are produced. This process involves meiosis and the formation of male gametes (sperm).

3. **Examine the Options**: The options provided are:
- A) Spermatogonia
- B) Glandular epithelium
- C) Sensory epithelium
- D) Germinal epithelium

4. **Analyze Each Option**:
- **Spermatogonia**: These are the precursor cells that develop into sperm, but they are not the lining of the seminiferous tubules.
- **Glandular epithelium**: This type of epithelium is involved in secretion but is not the type found in seminiferous tubules.
- **Sensory epithelium**: This type of epithelium is involved in sensory functions and is not related to the composition of seminiferous tubules.
- **Germinal epithelium**: This is the correct answer as it lines the seminiferous tubules and is responsible for the production of sperm through the process of spermatogenesis.

5. **Conclusion**: Based on the analysis, the correct composition of seminiferous tubules is **germinal epithelium**.

**Final Answer**: Germinal epithelium.
