Laryngeal Closure

• epiglottis, thyroid, arytenoid, cricoid, and tracheal rings
• assists in layrngeal vestibule closure, physically moves out of the way of bolus, and opens the cricopharygeal region.
• inversion of the epiglottis, vestibule closure (arytenoids to epiglottic base), false vocal fold closure, and true vocal fold closure.
• anterior and lateral sulcus, vallecula, lateral channels, pyriform sinus, and glottis.

Pharyngeal Stage

• tongue base retraction, laryngeal elvation, and anterior tilt of artenoids
• closure of soft palate, tongue base retraction, pharyngeal contraction, laryngeal elevation (vertical and anterior), laryngeal closure, and cricopharyngeal opening
• oral, nasal, pharyngeal, and laryngeal
• soft palate, layrngeal, pharyngeal, and upper esophageal sphincter

Cavities

• oral, nasal, pharyngeal, and laryngeal
