GI L22 - 25

1. 1Select all the vessels on the list that the celiac trunk branches to(and so the organs it connects to).

   1. ALeft gastric artery: stomach, lower esophagus, liver
   2. BSplenic artery: stomach, pancreas, spleen
   3. CCommon Hepatic artery: liver, pyloric stomach, pancreas, duodenum
   4. DColic arteries: ascending and transverse colon
   5. EIntestinal arteries: ileum, jejunum
   6. FIleocolic arteries: ileum, cecum, appendix
2. 2Which set of vessels (and organs) does the inferior mesenteric artery branch to?

   1. AColic, Intestinal, and Ileocolic arteries (ascending and transverse colon, ileum, jejunum, cecum, appendix)
   2. BLeft colic artery, Sigmoid arteries, Superior rectal artery (descending and sigmoid colon, rectum, anal canal)
   3. CLeft gastric, Splenic, and Common Hepatic arteries (stomach, lower esophagus, liver, pancreas, spleen, duodenum)
3. 3Vasculature development of the GI is set as early as 4 weeks, and early in development the gut length is the body length.

   1. ATrue
   2. BFalse
4. 4Match the epithelium type to the place you might find it in the GI.
   Simple squamous = [blank_start]peritoneal membrane[blank_end]
   Cuboidal = [blank_start]salivary glands[blank_end]
   Columnar = [blank_start]small intestine[blank_end]
   Stratified squamous = [blank_start]esophagus[blank_end]

   1. Aperitoneal membrane
   2. Bsalivary glands
   3. Csmall intestine
   4. Desophagus
5. 5The innermost basic layer of the gut tube is the [blank_start]mucosa[blank_end]. This begins with an epithelium in contact with the lumen, supported by the [blank_start]lamina propria[blank_end] (FCT), attached to the [blank_start]muscularis mucosa[blank_end].
   The next layer is the [blank_start]submoucosa[blank_end], which is FCT. It contains glands with ducts to the lumen, and has a nervous tissue structure called the [blank_start]Meissner's plexus[blank_end].
   Then there is the [blank_start]muscularis[blank_end], made of two muscle layers. The innermost layer is [blank_start]circular[blank_end] muscle and the outer is [blank_start]longitudinal[blank_end] muscle. It's nervous tissue is the [blank_start]Myenteric plexus[blank_end].
   Finally, the outermost basic layer is the [blank_start]adventitia[blank_end]. It is FCT which attaches the visceral periotonium.

   1. Amucosa
   2. Bsubmoucosa
   3. Cmuscularis
   4. Dadventitia
   5. Elamina propria
   6. Fmuscularis mucosa
   7. GMeissner's plexus
   8. HMyenteric plexus
   9. Icircular
   10. Jlongitudinal
6. 6Match the salivary glands to their secretions:
   Parotid: [blank_start]serous only[blank_end]
   Submandibular: [blank_start]serous and mucous[blank_end]
   Sublingual: [blank_start]mucous only[blank_end]

   1. Aserous only
   2. Bserous and mucous
   3. Cmucous only
7. 7Which adaptations of the stomach allow it to be a storage organ?

   1. ARugae and sphincters
   2. BRugae
   3. CSphincters
   4. DOblique muscles and rugae
   5. EOblique muscles
   6. FSphincters and oblique muscles
8. 8The stomach can expand up to 1.5L typically.

   1. ATrue
   2. BFalse
9. 9There are 4 types of special cells in the gastric pit.
   The most external (closest to the lumen) are the [blank_start]mucous neck cells[blank_end] which secrete mucous.
   Then there are [blank_start]chief cels[blank_end] which secrete [blank_start]enzymes[blank_end] such as pepsin.
   Below them are the [blank_start]parietal cells[blank_end] which secrete [blank_start]protons[blank_end] to make acid.
   The most internal (and farthest from the lumen) are [blank_start]endocrine cells[blank_end] that secrete hormones.

   1. Amucous neck cells
   2. Bchief cells
   3. Cenzymes
   4. Dparietal cells
   5. Eprotons
   6. Fendocrine cells
10. 10Which of these describes chief cells?

    1. AHas lots of ER, and apical zymogen granules
    2. BHas lots of mitochondria, and microvilli

11. 11What hormones do the endocrine cells secrete?

    1. APepsin and gastrin
    2. BGastrin and ghrelin
    3. CGhrelin and pepsin
12. 12Which structure controls the release of hepatopancreatic enzymes and bile salts into the duodenum?

    1. AHepatopancreatic ampulla
    2. BGreater duodenal papilla
    3. CSphinctre of Oddi
13. 13Choose the correct statement about the small intestine.

    1. ACells lining the villus have microvilli to increase their surface area, and last 12 - 14 days.
    2. BThe basic layer the plicae circulares are made from is the mucosa.
    3. CGlycocalyx sticks the brush border together, and increases surface area.
