Beginner Glottis Quiz

Q1. What structures together constitute the glottis?

• The epiglottis and aryepiglottic folds
• The vestibular folds and laryngeal ventricle
• The cricoid cartilage and trachea
• The true vocal folds and rima glottidis

Q2. What is the rima glottidis?

• The opening of the laryngeal ventricle
• The space between the vestibular folds
• The inlet of the larynx
• The opening between the true vocal folds

Q3. Which folds form the principal boundaries of the glottic opening?

• Aryepiglottic folds
• True vocal folds
• Pharyngoepiglottic folds
• Vestibular folds

Q4. Which cartilage provides the anterior attachment of the vocal folds?

• Epiglottic cartilage
• First tracheal cartilage
• Thyroid cartilage
• Corniculate cartilage

Q5. Which cartilages provide the posterior attachment of the vocal folds?

• Cuneiform cartilages
• Hyoid bone
• Corniculate cartilages only
• Arytenoid cartilages

Q6. What happens to the rima glottidis during quiet inspiration?

• It is covered by the epiglottis
• It closes completely
• It widens
• It remains fixed in the phonatory position

Q7. What happens to the vocal folds during normal phonation?

• They move into the laryngeal ventricle
• They are adducted
• They become completely relaxed and widely separated
• They are maximally abducted

Q8. Which intrinsic laryngeal muscle is the principal abductor of the vocal folds?

• Lateral cricoarytenoid
• Transverse arytenoid
• Thyroarytenoid
• Posterior cricoarytenoid

Q9. Which nerve provides motor innervation to the posterior cricoarytenoid?

• Recurrent laryngeal nerve
• Hypoglossal nerve
• Glossopharyngeal nerve
• Internal laryngeal nerve

Q10. Which statement best describes the glottis?

• It is identical to the entire laryngeal cavity
• It is the space between the false vocal folds
• It consists only of the epiglottis
• It comprises the true vocal folds and the opening between them
