Question

In the buccal cavity of frog, the internal nares are

• A. One
• B. Two
• C. Fused
• D. Absent

Answer 1

The correct option is B Two

The buccal or the oral cavity and pharynx are shared passageways for the movement of air in and out of the respiratory passage and movement of food and water into the digestive tube. The external nostrils lead into a nasal chamber, which opens into the buccal cavity through a pair of small apertures, called the internal nares. These are located on the roof of the buccal cavity near the anterior end. They play a role in respiration.
So, the correct answer is option B.
