Oropharyngeal and Esophageal Motility Flashcards
Name the 3 stages of the oropharyngeal phase
prehension
mastication
deglutition
What is involved in prehension?
scooping, licking, lapping
grasping of food and water
What is involved in mastication?
chewing, bolus formation
What is involved in deglutition?
rostro-caudal pharyngeal contraction, cricopharyngeal relaxation
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
Differentiation of esophageal disease
dysphagia (sometimes) regurgitation salivation delayed food ejection undigested food frequent odynophagia single-multiple swallowing attempts dyspnea/cough
Differentiation of gastric disease
vomiting salivation delayed food ejection digested food single swallowing attempts retching
General signs of orpharyngeal disorder
- dysphagia
- dropping food
- gagging
- salivation
- immediate food ejection
Causes of neuromuscular oropharyngeal dysphagias
myasthenia gravis lupus myositis hypothyroidism polymyositis brainstem disease
Steps of primary peristalsis
CES relaxation
esophageal peristaltic contraction
GES relaxation stimulated by swallowing
Steps of secondary peristalsis
esophageal peristaltic contraction
GES relaxation stimulated by esophageal distension
