Flashcards in Gastric Motility Deck (16):
1

Name the 5 parts of gastric anatomy

cardia
fundus
body (corpus)
antrum
pylorus

2

Name the 2 parts of gastric physiology

proximal stomach
distal stomach

3

What type of contractions does the proximal stomach have?

Slow-sustained contractions

4

What type of contractions does the distal stomach have?

Peristaltic contractions

5

Name the 4 physiological properties of the proximal stomach

receptive relaxation
accommodation
eructation
liquid emptying

6

Name the 4 physiological properties of the distal stomach

propulsion
trituration
retropulsion
solid emptying

7

What are the 5 factors regulating gastric emptying?

physics of emptying
post-prandial patterns
modifying factors
small intestinal regulation
interdigestive patterns

8

Physics of gastric emptying (3)

rate of emptying
pressure difference
pyloric resistance

9

Post prandial patterns of gastric emptying

liquids are emptied faster than solids

10

Modifying factors of gastric emptying (8)

gravity
temperature
volume
composition
acidity
osmolarity
viscosity
energy density

11

Small intestinal regulation of gastric emptying

acid receptor in proximal duodenum senses too much H+ and closes pylorus

12

Interdigestive patterns of gastric emptying

migrating motility complex

13

Clinical signs of oral cavity disease

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

14

Clinical signs of esophageal disease

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

15

Clinical signs of stomach disease

vomiting
salivation
delayed food ejection (digested)
single swallowing attempts
retching

16

Examples of delayed gastric emptying disorders

post-gastric dilatation/volvulus
infectious/inflammatory gastritis
gastric erosion and ulcer
autonomic neuropathy
electrolyte disturbance (K+, Ca2+, Mg2+)
metabolic disorders (uremia, addison's disease, diabetes mellitus)
