What are the phases of the swallow mechanism?
|
Oral
Pharyngeal Esophageal |
|
The swallow mechanism involves what cranial nerves? Pharyngeal? Esophageal phase?
|
Swallow mechanism = 5, 7, 12
Oral = not given Pharyngeal = 5, 10, 11, 12 Esophageal = Not given |
|
What things occur during the Swallow mechanism?
|
Oral prep phase --> Under voluntary control, uses CNs 5, 7, 12 --> Chewed food mixes with bolus --> Chewed food mixes with saliva to make bolus --> Bolus sitting between tongue and hard palate in groove formed by tongue
|
|
What occurs during the oral phase of swallowing?
|
Tongue begins ant. to post. pumping motion to move bolus post. --> bolus passes ant. tonsillar pillars --> Diseases in this phase can result with tongue dysfunction, inadequate dentition (impairs bolus formation)
|
|
What CNs are active during the pharynegeal phase of swallowing
|
5, 10, 11, 12
|
|
Wat occurs during pharyngeal phase of swallowing?
|
Larynx rises --> vocal folds close --> epiglottis closes --> soft palate separates nasal cavity from pharynx --> Blous passes through pharyngoesophageal sphincter (UES) into esophagus --> velopharyngeal spincter closes, preventing bolus regurgitation --> tongue and pharyngeal muscles propel bolus --> Larynx is closed off to bolus
Disease here caused by palatal dysfunction, pharyngeal constriction, laryngeal or epiglottic dysfunction |
|
What occurs during the esophageal phase of swallowing?
|
Food travels to stomach --> Pharyngoesophageal sphincter (PES) open to allow bolus into esophagus
Disease here may be motility disorder or mass/anatomical lesion |
|
Total time it takes for food to get from mouth to stomach?
|
9 sec
|
|
What kinds of things assoc. with swallowing can be affected as we age
|
Motility of upper esophageal sphincter, Motility of esophageal body, motility of lower esophageal sphincter, changes in sensory function

|
What things involved in swallowing can change as we age?
|
Thickening of mucosal coat, swallowing occurs more slowly, initiation of laryngeal and pharyngeal events takes longer, bolus may pool in pockets in pharyngeal recess, food bolus not well prepared to be swallowed, taste/temp/tactile sense change with age, intake may be too rapid, fatigue, change in endurance = inc. rick of aspriation, muscle atrophy
