A mass of food and/or liquid
Bolus
Includes cessation of mastication and posterior movement of the bolus where contact with the faucial pillars and palate triggers the swallowing reflex
Oral
vital for oral prep because it helps to elevate, retract, and protrude the mandible for mastication
temporalis
sensory experience that drives the desire to continue eating
gustation
This may occur if the epiglottis fails to invert
The process of preparing food to swallow (i.e., grinding/ crushing food)
Mastication
Pharyngeal
important to the oral stage because it elevates the tongue tip
superior longitudinal
stimulation of the pharynx, larynx, or bronchial passageway; involves laryngeal adduction, abdominal contraction, and forceful exhalation
sequential contractions that propel bolus through the digestive tract
peristalsis
A disorder of swallowing
Dysphagia
Purely reflexive stage of swallowing ends at LES
Esophageal
risorius
deficits in this stage can result in heartburn or GERD
esophageal
This type of instrumental exam does not provide a complete view of the oral stage
FEES
The process of swallowing
Voluntary stage of deglutition involves lip seal and cupping of tongue to keep food in oral cavity
Oral Prep
used to elevate the lower lip
mentalis
as the bolus spills over the back of the tongue into the pharynx, it may pool at this structure before moving to the UES
valleculae
this aids in digestion, controls oral bacteria, and cools foods
saliva
Oral Prep, Oral, Pharyngeal, and Esophageal
Stages of mastication and deglutition
Poor velum elevation, difficulty initiating a reflexive swallow, and poor laryngeal elevation would all be deficits at which stage?
Phrayngeal
important for the oral prep stage of swallowing and functions to keep food in the mouth by contracting to seal the oral cavity
orbicularis oris
respiration, phonation, articulation, and the nervous system are fundamental to this process
the swallowing process
this space between the gums and cheeks can hold bolus residue if the buccinator does not contract properly
Buccal cavity
