Swallowing Flashcards
when did swallowing become an important area for SLPs
-mid to late 1980s
what kind of response is swallowing?
-brainstem (instinctual) response, but needs to be modified due to size, texture, etc of the item being swallowed
Jeri Logemann
-closely associated with original work on oropharyngeal swallow
3 stages of swallowing
1) oral
2) pharyngeal
3) esophageal
oral stage
involves taking the food into the mouth and preparing it
pharyngeal stage
involves transport through the pharynx and into esophagus
esophageal stage
transport the food or drink to the stomach
what stages do SLPs work with?
oral and pharyngeal
oral containment
taking food into the mouth and preventing it from falling out
-lip closure
oral preparation
bring food to a consistency that can be swallowed
- chewing
- mixed with saliva
- bolus formation
oral transport
moving food back towards the pharynx (pushing food backwards)
what does the pharyngeal stage involve?
- moving bolus through the pharynx
- valving off the airway (trachea) and nasopharynx
- substages
cricopharyngeal relaxation
- mm relaxes to allow larynx to raise
- cricopharyngeal mm is the “valve” that keeps esophagus closed
velar elevation
-velum rises to close off the nasopharynx and prevent nasal regurgitation
VF closure
true and false VFs close to prevent material from entering trachea
