CD 663 SWALLOWING EXAM
QUESTIONS WITH COMPLETE
ANSWERS
Patient will tolerate the least restrictive diet to maintain maximum/adequate nutrition and
hydration without overt s/s of aspiration - answer-what is the ultimate goal of dysphagia
therapy?
Oral prep, oral transport, pharyngeal, oesophageal - answer-what are the 4 stages of
the swallow?
Mastication, bolus formation, bolus maintenance - answer-what are the 3 functions of
the oral preparatory phase?
Oral preparatory stage - answer-during this stage, the bolus is formed through
mastication and then prepared for transport.
Oral prep - answer-which stage is entirely under voluntary control?
Labial seal formed in front after bolus intake, buccal tension to assist in lip closure and
hold bolus in mouth, velum lowered and back of tongue elevated to form lingual-velar
seal posteriorly, vp port open for nasal breathing, rotary/lateral jaw and tongue
movement for mastication - answer-what are some of the components/actions that
make up the oral preparatory phase?
Mandible - answer-what is the only mobile bone of the face?
Jaw elevation/depression, jaw protrusion/retraction, lateral (side to side) movement,
rotary/grinding movement (lateralization) - answer-what are the essential movements of
the mandible for mastication?
Genioglossus, hyoglossus, palatoglossus, styloglossus - answer-what are the 4
extrinsic muscles of the tongue?
Alter tongue's position, allow for protrusion, retraction, and side-to-side movement for
manipulation of the bolus during mastication; elevate back of tongue so it makes contact
with velum, creating a seal in the back of the oral cavity to contain the bolus until it is
ready for transport - answer-what is the function of the extrinsic muscles of the tongue
during the oral prep stage?
Protrudes the tongue - answer-what is the function of genioglossus?
Depresses and retracts the tongue - answer-what is the function of hyoglossus?
, Raises back of tongue, depresses velum/opens vp port - answer-what is the function of
palatoglossus?
Tongue propels bolus upward and backward, tongue tip and sides elevate to alveolar
ridge, velum elevates, tongue base drops, - answer-what are some of the
components/actions that make up the oral transport phase?
Superior longitudinal, inferior longitudinal, transverse, vertical - answer-what are the 4
intrinsic muscles of the tongue?
Shortens tongue; elevates the tip and sides of the tongue superiorly - answer-what is
the function of the superior longitudinal muscle of the tongue?
Shortens tongue; curls the tip of the tongue inferiorly - answer-what is the function of the
inferior longitudinal muscle of the tongue?
Narrows and elongates the tongue - answer-what is the function of the transverse
muscle of the tongue?
Joins the superior and inferior longitudinal muscles; flattens and widens tongue -
answer-what is the function of the vertical muscle of the tongue?
These muscles affect the shape and size of the tongue and the fine movements of the
tongue tip - answer-what is the function of the intrinsic muscles of the tongue?
Cn vii (facial) controls taste for anterior 2/3 of tongue, cn ix (glossopharyngeal) controls
taste for posterior 1/3 of tongue - answer-which cranial nerves control special sensory
(taste/gustation) innervation for the tongue?
Cn v (trigeminal) controls anterior 2/3 of tongue, cn ix (glossopharyngeal) controls
posterior 1/3 of tongue - answer-which cranial nerves control general sensory
innervation for the tongue?
Pain, temperature, touch, pressure, vibration, proprioception - answer-what are types of
general sensory information?
Allows us to feel the size/amount, texture/consitency, location, and temperature of food
during mastication; helps us adapt how we chew, control the bolus, and know when
bolus is ready for transport - answer-how is general sensory info relevant to swallowing
during the oral prep stage?
Cn xii (hypoglossal) innervates all intrinsic and extrinsic muscles of the tongue except
for palatoglossus, which is innervated by cn x and xi (vagus and accessory) - answer-
which cranial nerves control motor innervation of the tongue?
