WebAug 17, 2009 · Answer The epiglottis is a leaf-like, fibroelastic structure, positioned between the base of the tongue and the laryngeal aditus. During swallow it appears to invert to cover the aditus as the 'first valve' of airway closure. Its apparent movement is actually passive. Current evidence points to external forces moving the epiglottis (Perlman, 92).

They were, however, unable to identify a similar threshold for pyriform sinus residue. WebMay 1, 2012 · Incomplete laryngeal vestibule closure can result in penetration of material. If this material is not squeezed out of the laryngeal vestibule, it is often aspirated after the swallow as gravity pulls it lower into the airway. If both laryngeal vestibule and glottic closure are incomplete, material may be aspirated during the swallow. in and out film cast
