Flashcards in Oropharyngeal and Esophageal Motility Deck (11):
1

Name the 3 stages of the oropharyngeal phase

prehension
mastication
deglutition

2

What is involved in prehension?

scooping, licking, lapping
(grasping of food and water)

3

What is involved in mastication?

chewing, bolus formation

4

What is involved in deglutition?

rostro-caudal pharyngeal contraction, cricopharyngeal relaxation

5

Differentiation of oral cavity disease

dysphagia (difficulty eating)
salivation
gagging
abnormal drinking
dropping food
immediate food ejection
undigested food
occasional odynophagia (multiple swallowing attempts)
discharge

6

Differentiation of esophageal disease

dysphagia (sometimes)
regurgitation
salivation
delayed food ejection
undigested food
frequent odynophagia
single-multiple swallowing attempts
dyspnea/cough

7

Differentiation of gastric disease

vomiting
salivation
delayed food ejection
digested food
single swallowing attempts
retching

8

General signs of orpharyngeal disorder

1. dysphagia
2. dropping food
3. gagging
4. salivation
5. immediate food ejection

9

Causes of neuromuscular oropharyngeal dysphagias

myasthenia gravis
lupus myositis
hypothyroidism
polymyositis
brainstem disease

10

Steps of primary peristalsis

CES relaxation
esophageal peristaltic contraction
GES relaxation stimulated by swallowing

11

Steps of secondary peristalsis

esophageal peristaltic contraction
GES relaxation stimulated by esophageal distension
