| Food is collected into a bolus |
|
Definition
|
|
Term
| Bolus is held anteriorly and laterally by the tongue against the hard palate |

|
Term
| Bolus passes the anterior faucial arches and triggers the pharyngeal response |
|
Definition
| Transition between oral and pharyngeal |
|
|
Term
| Considered to be the most physiologically important stage. Why? |
|
Definition
Pharyngeal
1. Airway Protection
2. Opening of the UES
3. Downward propulsion of bolus because of pharyngeal constriction |
|
|
Term
| Velum elevates to achieve velopharyngeal closure |

Term
Pharyngeal Contraction Begins
|
|
Definition
|
|
Term
UES/PE Segment/Cricopharyngeus opens due to
1. relaxation of the UES
2. elevation of the larynx
3. pulsion of the bolus because of pharyngeal contriction |

Term
| Primary Peristalsis begins. What is it? |
|
Definition
| Esophageal Stage. Striated muscle moves the bolus down after the pharyngeal response is triggered |
|
|
Term
| Secondary Peristalsis begins. What is it? |
|
Definition
| Esophageal Stage. Initated in response to local distention (esophagus extends because there is something in it). The bolus will be emptied into the stomach. |
