59
Q

Oral preparatory phase

A

food/liquid taken into the mouth

60
Q

Difference between food and liquid in the mouth

A

Liquids: linguavelar valve closed, bolus positioned for transit
Foods: – bolus positioned for mastication. Mastication
including rotary mandible movement, crushing of bolus.
Tongue moves bolus for mastication.

61
Q

Oral transit stage

A

prepared bolus is propelled by tongue to palate progressive anterior to posterior contact.
a. Liquids typically all at once
b. Solids aggregate in pharynx until pharyngeal
response begins

62
Q

Pharyngeal phase onset

A

Pharyngeal response begins
a. Linguavelar closure (liquid) ends, velopharyngeal
closure begins
b. Bolus head enters pharynx (passes faucial arch)
1. Young: a occurs before b
2. Aging: b occurs before a
a. Prolonged stage transition
c. Disordered: a begins abnormally later than it
should based on age

63
Q

Pharyngeal transit stage

A 
Velopharyngeal closure completes
Pharyngeal tube constriction begins
UES resting tone inhibition
Increases UES compliance
Vocal folds adduct
Hyolaryngeal excursion (anterior, superior)
Traction forces on larynx UES
Epiglottis inverts, vocal folds adduct
Airway closes, breathing stops
Bolus enters UES, clears UES
Hyolaryngeal excursion ends, UES closes
Structures return to rest
64
Q

Esophageal transit stage

A

UES remains tightly closed
Superior to inferior “peristalsis” (constriction)
of esophageal muscles
Circular muscles constrict top to bottom
Longitudinal muscles shorten
Net result is propulsion
LES (tightly closed at rest) “relaxes” when
pressure of bolus (intrabolus pressure) rises
LES opens, bolus enters stomach
Bolus clears LES
LES closes
