55
instrument to measure tongue force
Iowa Oral Pressure Instrument (IOPI)
test to measure muscle function during swallowing
Electromyography (EMG)
tool for measuring swallowing functionality
Modified Barium Swallow Study (MBSS)
Test that involves tube with camera through nose, into pharynx, looks at vocal folds, back of tongue
nasoendoscopy
Another name for nasoendoscopy
FEES - Fiber endoscopic eval of swallowing
In infants, the ___ locks behind the __ so the child can breathe and feed at the same time
velum; epiglottis
Infants find food through the ___ reflex, which is triggered by stimulation to the __ or __
rooting; lips; cheek
The sucking reflex is first this ___
tongue protrusion in and out of mouth in prep of nipple
what are the three stages of swallowing?
Oral
Pharyngeal
Esophageal
two substages of oral stage of swallowing
preparatory and transport
how many muscles are involved in the oral prep stage?
19
Which five non-tongue VII muscles are involved in the oral prep stage?
- Orb oris
- Mentalis
3, 4. Buccinator and risorius - Digastric
what are the six muscular actions of the oral prep stage?
- Lips close to keep food inside
- SP lowers to breathe through nose
- Jaw chews
- Back of tongue bunches to seal in food
- Tongue moves food around, mixes with saliva
- Cheeks contract so food doesn’t get between gums and cheeks
which six V muscles are involved in oral prep?
- Masseter
- Temporalis
- Medial pterygoid
- Lateral pterygoid
- Mylohyoid
- Digastric
which six XII tongue muscles are involved in oral prep?
1) geniohyoid
2) superior long.
3) inf. long.
4) vert tongue muscles
5) genioglossus
6) styloglossus
what two X and XI muscles are involved oral prep?
- Palatoglossus
- Palatopharyngeus
what are the five muscular actions of the oral transport stage?
1) Tongue base drops and tongue pulls posteriorly
2) Chewing stops
3) Ant. tongue elevates to HP
4) VF close
5) Tongue tip and dorsum move to squeeze bolus posteriorly (squeezing moves front to back)
how many muscles are involved in the oral transport stage?
9
which four V muscles are involved in the oral transport stage?
- Masseter
- Temporalis
- Internal pterygoid
- Mylohyoid
which four XII muscles are involved in oral transport stage?
- Sup. long.
- Vertical
- Genioglossus
- Styloglossus
Which X and XI muscle is involved in the oral transport stage?
- Palatoglossus
what happens in the pharyngeal stage of swallowing?
bolus moves from oral cavity through pharynx to esophageal entrance
what does UES stand for?
upper esophageal sphincter
what are the five main events in the pharyngeal stage of swallowing?
- bolus gets to faucial pillars
- Bolus propelled through pharynx to relaxed UES
- Tight seal protects airway - VF, false folds, epiglottis, SP
- Respiration stops for milliseconds
- Food passes over epiglottis, gets divided into two equal masses, moves through pyriform sinuses to esophagus
how many muscles are involved in the pharyngeal stage of swallowing?
27
what are the three V muscles involved in the pharyngeal phase?
- Mylohyoid
- Digastricus
- Tensor veli palatini
what are the two VII muscles involved in the pharyngeal stage?
- Digastricus
- Stylohyoid - elevates hyoid and larynx
what are the nine XII muscles involved in the pharyngeal stage?
7 are tongue, 3 hyoid
- Geniohyoid
- Genioglossus
- Styloglossus
- Hyoglossus
- Thyrohyoid
- Sup. longitudinal
- Inf. longitudinal
- Transverse
- Vertical
what are the six muscles innervated by BOTH X and XI that are involved in the pharyngeal stage?
Lots of palate, pharyngeal constrictor
- Palatoglossus
- Levator veli palatini
- Musculus uvulae
- Palatopharyngeus
- Inf constrictor - Cricopharyngeus
- Middle pharyngeal constrictor
what is the one muscle ONLY innervated by XI that is involved in the pharyngeal stage?
Salpingopharyngeus
