Advanced Epiglottis Quiz

Q1. Why does the epiglottis not function as a simple passive lid that alone seals the airway?

• The epiglottis never moves during swallowing
• Only the cricoid cartilage closes the airway
• Airway closure depends on coordinated laryngeal and pharyngeal movements in addition to epiglottic inversion
• Airway protection is produced solely by the soft palate

Q2. Which anatomical relationship explains why the vallecula is useful during direct laryngoscopy?

• It contains the recurrent laryngeal nerve
• It is inside the cricoid cartilage
• It lies between the tongue base and epiglottis and can be used to elevate the epiglottis indirectly
• It lies between the vocal folds and directly opens the rima glottidis

Q3. Which ligament acts as a direct tether between the epiglottis and thyroid cartilage?

• Lateral thyrohyoid ligament
• Hyoepiglottic ligament
• Cricotracheal ligament
• Thyroepiglottic ligament

Q4. How does the hyoepiglottic ligament differ from the thyroepiglottic ligament?

• It connects the cricoid directly to the trachea
• It connects the epiglottis to the hyoid rather than the thyroid cartilage
• It joins the two arytenoid cartilages
• It forms the vocal ligament

Q5. Which boundary of the laryngeal inlet is formed by the epiglottis?

• Anterior boundary
• Posterior boundary
• Inferior boundary
• It forms no part of the inlet

Q6. Why is preserved sensation around the laryngeal surface of the epiglottis important?

• It provides motor innervation to the diaphragm
• It directly contracts the vocalis muscle
• It contributes to protective airway reflexes
• It controls tongue protrusion

Q7. Which anatomical pathway carries afferent information from the supraglottic laryngeal mucosa toward the brainstem?

• Internal laryngeal nerve to superior laryngeal nerve to vagus nerve
• External laryngeal nerve to glossopharyngeal nerve
• Phrenic nerve to accessory nerve
• Recurrent laryngeal nerve to hypoglossal nerve

Q8. How do the aryepiglottic folds contribute functionally to airway protection?

• They abduct the vocal folds during inspiration
• They open the esophagus by pulling the cricoid anteriorly
• They elevate the soft palate
• They can narrow the laryngeal inlet

Q9. Why can marked swelling of the epiglottis threaten ventilation?

• Swelling directly obstructs both main bronchi
• Swelling can narrow the laryngeal inlet
• Swelling paralyzes the diaphragm
• The epiglottis lies inside the nasal cavity

Q10. Which statement best integrates epiglottic anatomy?

• The epiglottis is a paired cartilage that articulates with the cricoid
• The epiglottis is a rigid hyaline ring responsible for vocal fold abduction
• The epiglottis is an intrinsic laryngeal muscle that closes the glottis
• The epiglottis is a flexible elastic cartilage whose attachments and surrounding folds integrate it into the laryngeal inlet and swallowing mechanism
