In Frog, throat is raised during buccopharyngeal and pulmonary respiration by means of

Options

A. Hypoglossus muscles
B. Submentalis muscles
C. Sternohyoid muscles
D. Petrohyoid muscles

Answer

To answer the question regarding how the throat of a frog is raised during buccopharyngeal and pulmonary respiration, we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Understanding Frog Respiration**:
- Frogs have two methods of respiration: buccopharyngeal respiration and pulmonary respiration.
- Buccopharyngeal respiration occurs through the buccopharyngeal cavity, while pulmonary respiration occurs through the lungs when the frog is on land.

2. **Identifying the Role of Muscles**:
- During both types of respiration, certain muscles are involved in the process of raising the throat to facilitate air intake and expulsion.

3. **Muscles Involved**:
- The options given are hypoglossus muscles, submentalis muscles, sternohoid muscles, and petrochoid muscles.
- Among these, the petrochoid muscles play a crucial role in the respiratory process.

4. **Function of Petrochoid Muscles**:
- The contraction and relaxation of the petrochoid muscles are responsible for raising the throat during both buccopharyngeal and pulmonary respiration.
- This action aids in the process of inspiration (intake of air) and expiration (release of air).

5. **Conclusion**:
- Therefore, the throat of a frog is raised during buccopharyngeal and pulmonary respiration by means of the petrochoid muscles.

### Final Answer:
In frog, the throat is raised during buccopharyngeal and pulmonary respiration by means of the **petrochoid muscles**.
