Role of saliva
maintain oral moisture, reduce tooth decay, assists in digestion, natural neutralizer of stomach acid
Pharyngeal structures involved in degulutition
Pharyngeal constrictors
superior, medial, inferior
Glossopharyngeus muscle
responsible for tongue base retraction
Pyriform Sinuses
formed by the space between the inferior constrictor and thyroid cartilage
Upper Esophageal Sphincter formed by
2 main functions
cricoid lamina and cricopharyngeal region
allow bolus to enter
prevent backflow
UES pressure
most pressure immediately prior to swallow and during inspiration
Esophogus' two layers
inner circular
outer longitudinal
larynx in swallowing
keeps food from entering the airway
topmost structure of the larynx is the ____
Epiglottis is attached into the hyoid bone and the valleculae is divided by the _____
hyoepiglottic ligament
Wedge-shaped space formed between the base of the tongue and the epoglottis ______
What are the pharyngeal recesses or side pockets?
valleculae and two pyriform sinuses
Opening to the larynx is the ____ and bound by ___, ___, ____, and _____
laryngeal vestibule

epiglottis, aryepiglottic folds, arytenoid cartilage, false vocal folds
cricoarytenoid and interarytenoid muscles adduct the arytnoids an close_____
the true vocal folds across the top of the airway
during swallow arytnoids
adduct and tilt anteriorly
space b/w true and false vocal folds
larngeal ventricle
the last level of airway protection is the _____
true vocal folds
4 phases of deglutition
oral preparatory
oral phase
pharyngeal phase
esophageal phase
respiration _____ during the pharyngeal phase
swallowing frequency is greatest during ____ and least during ____
20% of normal swallowers
Tongue Thrust Pattern
bolus pushes out of mouth or against tongue and anterior teeth

seen in CP or frontal lobe damage
normal oral stage requires
intact labial, palatal and buccal muscles, lingual movement, and ability to breath through nose
Trigger point
At latest when base of tongue crosses mandible

at anterior faucial arches for normal young
Sensory portion of pharyngeal swallow, nerves
Motor portion of pharyngeal swallow, nerves
steps after trigger in pharyngeal swallow
elvation/retraction of velum
elevation/anterior mvtm. of hyoid and larynx
closure of larynx
open cricopharyngeal sphincter
ramping of base of tongue
progressive contraction in pharyngeal constrictors
velarpharyngeal closure allos for ___ in the pharynx
pressure buildup
larynx and hyoid elevation and anterior movement contribute to what?
elevation- closure of airway
anterior movement- opening of UES
Cricopharyngeal opening steps
tension in cricopharyngeal muscle=sphincter release
laryngeal anterior superior motion= sphincter begins to open
larynx moves up= sphincter open
Pressure of bolus determines how wide
Tongue base should make complete contact with _____ during swallow
pharyngeal wall
progressive contraction of muscular tube. (esophagus)

NOT the pharynx (thats progressive contraction but not a muscular tube)
Pressure is always applied to the ____ of the bolus
If no pharyngeal swallow is triggered
food may get stuck in the valleculae or pyriform sinuses

water may bounce into the open airway.

OR drain from valleculae to the aryepiglottic folds to the pyriform sinus
Pharyngeal transit time measured from
trigger point through cricopharyngeal juncture into the esophogus
purpose of epiglottis
direct food around airway rather than over airway
2 difference in infant vs adult swallowing
infat: less laryngeal elevation, posterior pharyngeal wall moves further anteriorly
with age _____ of bones and cartilage
thyroid, cricoid, hyoid
Cervical arthritic changes may impinge on the ____ wall, decreasing ____
difference b/w necessary movement and actual movement
When airway is closed during swallow it is known as the
apneic period
respiration interupted during the ___ stage
exhalation, so that when it begins again exhalation will clear extra residue
___ creates the biggest changes in oralpharyngeal swallow
bolus volume
as viscosity increase
pressure ____
muscle activity ___
patients with respiratory problems may not be able to ____
cup drink
4 components necessary fr swallow
1. oral propulsion of bolus into pharynx
2. airway closure
3. UES opening
4. tongue base-pharyngeal wall propulsion
Palatine Tonsils
b/w faucial arches
Lingual Tonsils
@ base of tongue
posterior pharyngeal wall
