- 1artery that supplies the foregutCeliac trunk
- 2where does the foregut endduodenal papilla where the common bile duct drains
- 3how far does the midgut travel and endright 2/3rd marker on the transverse colon
- 4where does the hindgut endsleft 1/3 of transverse colon
- 5Hindgut derivatives are supplied by branches of theinferior mesenteric a
- 6Midgut derivatives are supplied by branches of thesuperior mesenteric
- 7foregut derivatives in the abdomen are supplied by branches of theceliac artery

rectum - 11how does the mid gut communicate with the yolk sacvitelline duct
- 12what does the dorsal mesentary becomegreater omentum
- 13Which of the following is NOT derived at least in part from the midgut? lung duodenum jejunum ileum transverse colonLung
- 14uring development of the gut: the pancreas remains retroperitoneal throughout its development. the liver is derived from the midgut. the hindgut is supplied by the celiac artery. the smooth muscle in the wall of the esophagus is derived from splanchnic mesoderm. ALL of the abovethe smooth muscle in the wall of the esophagus is derived from splanchnic mesoderm
- 15During development of the gut: the pancreas is initially intraperitoneal but becomes secondarily retroperitoneal the liver arises as ventral and dorsal endodermal buds that then fuse into a single organ the foregut is supplied by the superior mesenteric artery the entire lumen of the GI tract remains open throughout development ALL of the abovethe pancreas is initially intraperitoneal but becomes secondarily retroperitoneal
- 16what structure is in the dorsal mesnetarythe spleen and pancreas
- 17the ventral mesentatrayliver
- 18what is left of the dorsal mesogastriumgastro renal ligament
splenorenenal ligament - 19forms the dorsoventral hairpin foldMidgut
- 20early week 6 the the cecum sprouts thevermiform appendix
when the jejunum and ileum are thrown into loops - 21hindgut in relation to the cloacal membranedeep
- 22diverticulum of the cloacaAllantois
- 23in week 4 and 6 the cloaca is partitioned by a superiortourneaux fold and two two lateral rathke folds which fuse to form the urorectal septum
- 24separates the posterior anorectal canal and anterior urogenital sinusurorectal septum
- 25separates the endodermal and ectodermal partsanal membrane
