Voice box is another name used for___________?
Correct answer: C. Larynx
- A. Buccal cavity
- B. Pharynx
- C. Larynx
- D. Chest Cavity
Explanation
The larynx is called the voice box because it contains the vocal cords, which vibrate as air passes between them. The pharynx is a shared passage for food and air but does not contain the vocal cords. The likely mistake is choosing pharynx because it lies just above the larynx in the throat.
