A

tracheal rings

20
Q

opening between vocal cords

21
Q

 Superior opening of the larynx
 Routes food to the larynx and air toward the trachea

A

epiglottis

22
23
are the superior pair of ligaments
Vestibular folds (false vocal cords)
24
 are the inferior ligaments.  vibrate with expelled air. This ability of the vocal folds to vibrate allows us to speak
Vocal folds (true vocal cords)
