Question

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

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

Answer 1

The correct option is D Petrohyoid muscles

The respiration which takes place through a buccopharyngeal cavity, it is called buccopharyngeal respiration. Frog respires through the lungs when it lives on land during leaping and jumping, the demand for oxygen increased. Now, the petrohyoid muscle contracts and the carbon dioxide is thrown outside. This is called as pulmonary respiration.

So the correct answer is 'Petrohyoid muscles'.
