tract motility

what does the submucosal (meissner) plexus control? (2) - Correct Answer - movements of
muscularis mucosae

- secretions of mucosa



what is the myenteric (auerbach) plexus and where is it? what does it control? what does it regulate?
- Correct Answer - parasympathetic ganglia btwn layers of muscularis externa

- controls muscularis externa contractions

- regulates enzymatic output of accessory organs

,what are the 3 serous membranes of the digestive tract? - Correct Answer - mesenteries

- intraperitoneal organ

- retroperitoneal organ



what do mesenteries do? (2) what do they contain? - Correct Answer - loosely suspend GI tract from
abdominal wall, provide passage for blood vessels and nerves

- contain lymph nodes & vessels



what do intraperitoneal organs have on both sides? what are the 4 intraperitoneal organs? - Correct
Answer - messentery on both sides

- stomach, liver, jejunum, ileum



retroperitoneal organs have what on one side only? what are the 2 retroperitoneal organs? - Correct
Answer - messentery on ventral side only

- duodenum, most of pancreas



what is the pathway through the GI tract (4)? - Correct Answer - mouth

- pharynx

- esophagus

- stomach



what does the mouth do? - Correct Answer - begins carbohydrate & lipid digestion
