Answer 13

Vestibular folds (false vocal cords)

Vocal folds (true vocal cords)

Question 14

Infraglottic Cavity

Question 16

What is the name for the small diverticulum within the laryngeal ventricle? It contains glands which lubricate the vocal folds, called the “oil can” of the vocal folds. Hoarseness from singing or speaking is often from depletion of the lubricant.
