|
oral prep/ oral/ pharyngeal /esophageal
|
|
|
what is the physiology associated with the ORAL Preparatory phase?
|
mastication of food in the mouth
Labial seal Adequate facial muscle tone Rotary and lateral movement of tongue and mandible Larynx and pharynx are at rest |
|
|
During the oral preparatory phase what anatomy is associated?
|
lips-cheeks-tongue-hard palate -alveolar ridge
|
|
|
During the Oral phase what anatomy is associated
|
Lips
Cheeks Tongue Hard palate Soft palate |
|
|
what is the physiology associated with the oral phase
|
Begins with posterior movement of the food/liquid
Stripping action Lateral edges and tongue tip are anchored against the alveolar ridge Transit time is approximately 1-1.5 seconds |
|
|
When does the pharyngeal phase begain
|
Begins when the food/liquid first passes through the faucial arches and triggers a swallow response
Approximately 1 second |
|
|
what is the physiology associated with the pharyngeal phase
|
Velopharyngeal closure
Elevation and anterior movement of the hyoid and larynx Closure of the larynx Tongue base and pharyngeal wall action Cricopharyngeal opening |
|
|
What is the anatomy associated with the pharyngeal phase
|
Soft palate
Epiglottis Valleculae Aryepiglottic fold Pyriform sinus Larynx Cricopharyngeal muscle |
|
|
during the esophageal phase what physiology is associated
|
Begins with the food/liquid enters the opening to the esophagus and ends when the bolus enters the stomach
Transit time varies 8-20 sec Peristalsis |
