Flashcards in GI motility Deck (14):
1

which vitamins are fat soluble?

DEAK

2

phases of GI activity

cephalic, gastric, intestinal, interdigestive (also Migrating Motor Complex)

3

phases of swallowing

oral, pharyngeal, esophageal

4

Afferent nerves controling swallowing

superior laryngeal, terminates in Nucleus of Tractus Solitarius in medulla

5

Post ganglionic neuron body locations for control of swallowing

Dorsal motor nucleus of vagus and nucleus ambiguus

6

central pattern generator location for swallowing

bilaterally in the medulary reticular formation

7

primary vs secondary peristalsis

primary is cns generated continuation of pharyngeal phase of swallowing via vagus nerve. Secondary is reflex activated by esophageal distension

8

where is the main storage part of stomach? mixing part?

proximal. Antrum.

9

hormone increasing gastric contraction? decreasing?

gastrin. secretin and CCK

10

which things move through stomach more slowly

lipids are slower than solids. solids are slower than liquids. Hyperosmolar sol'ns are also moved slowly

11

does peristalsis require ANS input

no

12

motor patter directed toward mixing in intestine

segmentation

13

shuttling

moving material in large bowel back and forth

14

MMC: how often? require ANS?

90 minutes. no
