Scrotal sacs of man and rabbit are connected with the abdominal
cavity by

Options

A. inguinal canal
B. Haversian canal
C. vaginal cavity
D. spermatic canal

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the anatomical connection between the scrotal sacs of man and rabbit and the abdominal cavity.

2. **Identifying the Options**: The options provided are:
- Inguinal canal
- Haversian canal
- Vaginal cavity
- Spermatic canal

3. **Analyzing Each Option**:
- **Inguinal Canal**: This is a narrow passage that connects the peritoneal cavity (the abdominal cavity) to the scrotal sac. In human males, it serves as a pathway for structures such as the spermatic cord. In rabbits, the scrotal sacs are migratory and can withdraw into the abdominal cavity through this canal.
- **Haversian Canal**: This is part of the bone structure and contains blood vessels. It is not related to the scrotal sacs, making this option incorrect.
- **Vaginal Cavity**: This is part of the female reproductive system and does not pertain to the scrotal sacs, so this option is also incorrect.
- **Spermatic Canal**: This term generally refers to the spermatic cord, which suspends the testis in the scrotum. However, it does not describe the connection to the abdominal cavity.

4. **Conclusion**: The correct answer is the **inguinal canal**, as it is the structure that connects the scrotal sacs to the abdominal cavity in both humans and rabbits.

5. **Final Answer**: The scrotal sacs of man and rabbit are connected with the abdominal cavity by the **inguinal canal**.
