The testis

Options

A. is covered by a serous membrane called tunica albuginea
B. is divided into testicular lobules that contain seminiferous tubules
C. contains Leydig cells that provide nutrition to the germ cells
D. produces spermatogonia from spermatocytes

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Testis**: The testis is an essential male reproductive organ responsible for producing sperm and hormones. It has a specific structure that includes various components.

2. **Evaluating the Statements**:
- **Statement 1**: "It is covered by a serous membrane called tunica albuginea."
- This statement is partially correct. The testis is indeed covered by a membrane called tunica albuginea, but it is not a serous membrane; it is a fibrous membrane.
- **Statement 2**: "It is divided into testicular lobules that contain seminiferous tubules."
- This statement is correct. The testis is divided into approximately 250 testicular lobules, each containing seminiferous tubules where sperm production occurs.
- **Statement 3**: "It contains Leydig cells that provide nutrition to the germ cells."
- This statement is incorrect. Leydig cells produce hormones (like testosterone) and provide nutrition to the developing sperm, not directly to the germ cells.
- **Statement 4**: "It produces spermatogonia from spermatocytes."
- This statement is also incorrect. The testis produces spermatocytes from spermatogonia, not the other way around.

3. **Identifying the Correct Statement**: After evaluating all the statements, the only correct statement is that the testis is divided into testicular lobules that contain seminiferous tubules.

4. **Conclusion**: The correct answer is that the testis is divided into testicular lobules that contain seminiferous tubules.

**Final Answer**: The correct statement regarding the testis is that it is divided into testicular lobules that contain seminiferous tubules.
