CETP Exam Prep - Dysphagia
swallowing physiology - phases
oral phase (voluntary)
pharyngeal phase (involuntary)
esophageal phase (involuntary)
oral phase (2 componants)
oral preparation
oral transport
oral preparation
manipulation and mastication of food into a blous
involves lips, jaw, tongue, soft palate, buccal and mastication muscles
oral transport
tongue tip and sides contract
anterior to posterior movement
bolus and tongue motion near faucial pillars and tongue based
pharyngeal phase steps
pharyngeal phase initiated
bolus near tongue base
bolus nears upper esophageal sphincter (UES)
initiation of pharyngeal phase
laryngeal and hyoid elevation
velopharyngeal closure
epiglottis closes airway
esophageal phase
food transports from pharynx to stomach
tongue muscles - types (2)
intrinsic
extrinsic
intrinsic tongue muscles - where
originate and extend within tongue
intrinsic tongue muscles (4)
, superior longitudinal
inferior longitudinal
transverse
vertical
extrinsic tongue muscle - where
originate outside tongue and extend within
extrinsic tongue muscles (4)
genioglossus
hyoglossus
styloglossus
palatoglossus
oral preparation swallow disorder characteristics
reduced lip closure
reduced tongue ROM
reduced tongue shaping
aspiration
reduced labial and buccal tension
tongue thrust, reduced control
oral preparation swallow disorder symptoms
cannot hold/form cohesive bolus
premature bolus loss
aspiration before swallow
food falls in anterior and lateral sulci
oral phase swallow disorder characteristics
reduced sensation
apraxia of swallow (uncoordinated)
tongue thrusts
reduce tongue movement+strength+elevation
oral phase swallow disorder symptoms
delayed oral onset of swallow
searching tongue movements
residue on tongue
incomplete tongue to palate contact
triggering pharyngeal phase swallow disorder characteristics
delayed pharyngeal swallow/not triggered
