AThe epiglottis and the cricoid cartilage together
BThe arytenoid and corniculate cartilages together
CThe vestibular folds, vocal cords and their gap
DThe thyroid lamina and the fibroelastic membrane
Answer & Solution
Correct answer: C. The vestibular folds, vocal cords and their gap
1. The glottis is not a single structure but a set of folds plus the space between them.
2. It comprises the vestibular folds, the true vocal cords and the space between these folds.
3. So the third option is correct.
4. The epiglottis rests on the glottis when closed but is a separate flap, which rules out the first option.
