Gastric Motility Flashcards
Name the 5 parts of gastric anatomy
cardia fundus body (corpus) antrum pylorus
Name the 2 parts of gastric physiology
proximal stomach
distal stomach
What type of contractions does the proximal stomach have?
Slow-sustained contractions
What type of contractions does the distal stomach have?
Peristaltic contractions
Name the 4 physiological properties of the proximal stomach
receptive relaxation
accommodation
eructation
liquid emptying
Name the 4 physiological properties of the distal stomach
propulsion
trituration
retropulsion
solid emptying
What are the 5 factors regulating gastric emptying?
physics of emptying post-prandial patterns modifying factors small intestinal regulation interdigestive patterns
Physics of gastric emptying (3)
rate of emptying
pressure difference
pyloric resistance
Post prandial patterns of gastric emptying
liquids are emptied faster than solids
Modifying factors of gastric emptying (8)
gravity temperature volume composition acidity osmolarity viscosity energy density
Small intestinal regulation of gastric emptying
acid receptor in proximal duodenum senses too much H+ and closes pylorus
Interdigestive patterns of gastric emptying
migrating motility complex
Clinical signs of oral cavity disease
dysphagia salivation gagging abnormal drinking dropping food immediate food ejection (undigested) occasional odynophagia multiple swallowing attempts discharge
Clinical signs of esophageal disease
some dysphagia regurgitation salivation delayed food ejection (undigested) frequent odynophagia singe-multiple swallowing attempts dyspnea/cough
Clinical signs of stomach disease
vomiting salivation delayed food ejection (digested) single swallowing attempts retching
