MBSImP
Pharyngeal Contraction, component 13, is scored in which plane?
Anterior-Posterior
Which muscles are involved in bolus preparation/mastication?
Hypoglossal
Masseter
Geniohyoid
_____ pressure is applied to _____ of the bolus throughout the upper aerodigestive tract
Positive - Tail
What event occurs in a respiratory cycle during the pharyngeal swallow in most adults?
Pause or cessation of respiration
LABEL 1
Soft Palate
Valleculae
Epiglottis
Which of the following component/s are not a physiological function?
A) Oral residue B) Lip closure C) Pharyngeal residue
D) A&B E) A&C
E
Which cranial nerve is responsible for innervating the tensor veli palatine that tenses the soft palate and facilitates bolus hold?
Cranial Nerve V – the motor branch of the Trigeminal Nerve
When does the pharyngeal swallow typically trigger?
When head of bolus reaches the ramus of mandible and back of tongue
The most typical pattern during normal liquid swallowing from a cup is ____________
Exhalation-Swallow-Exhalation
LABEL 2
Oral tongue
Posterior pharyngeal wall
Arytenoids
How does lip closure (Component One) contribute to swallow function?
1) Facilitate oral containment
2) Generate positive intra-oral pressure on bolus tail
Name one component of swallow physiology on the MBSImP™ and primary muscle involved in the function of that component
Lip closure – orbicularis oris
The pharyngeal stripping wave should not be termed “peristalsis” because?
There may be volitional modification of the pharyngeal constrictor action
Normal liquid swallowing most commonly occurs when?
During exhalation at mid-low lung volume
Label 3
Mandible
Vocal folds
Name the three dimensions that may be involved in visual judgments of PES impairment.
Distension, Duration, Obstruction
_______ and _______ are the primary medulla nuclei involved in motor and sensory innervation of swallowing
Nucleustractussolitarius (NTS)
Nucleusambiguus (NA)
Is it accurate to describe swallowing physiology by dividing the swallow into oral, pharyngeal, and esophageal phases? Why?
No. Swallowing is a synergistic movements of structures relative to bolus flow.
Name a respiratory swallow pattern that is suboptimal.
Inhalation-Swallow-Inhalation
Label 4
Base of tongue
Hyoid Bone
Pharyngoesophageal Segment (PES)
Laryngeal Elevation, component 8, is assessed by judging what?
Contact of the arytenoid cartilages with the base of the epiglottis when the epiglottis is at it's most horizontal position
Which cranial nerves have a primary role in triggering a timely pharyngeal swallow?
Cranial nerve IX, glossopharyngeal
It is a motor response and lacks the necessary brevity and predictability associated with a true reflex
Name a mechanical advantage of swallowing during exhalation at mid-to-low lung volume
Facilitates superior-anterior hyolaryngeal movementFacilitates esophageal clearance
Label 5
Valleculae
Arytenoid
PES
