Flashcards in Peritoneum and Peritoneal Reflections Deck (14):
What are the 2 types of visceral peritoneum?
Mesenteries and visceral ligaments (aka omenta)
What are the 4 mesenteries and what do each of them connect?
1. Mesentery - fromloops of intestine to body wall
2. Mesoappendix - from appendix to body wall
3. Transverse mesocolon - from transverse colon to body wall
4. Sigmoid mesocolon - from sigmoid colon to body wall
What are the 6 visceral ligaments?
Lesser omentum (2 parts: hepatogastric and hepatoduodenal ligaments)
Falciform ligament (between left and right liver)
Coronary ligament (top of liver)
Gastrosplenic ligament (connects stomach and spleen)
Splenorenal ligament (spleen and kidney)
What are the 3 peritoneal sacs?
These are spaces in the peritoneal cavity:
Lesser omental sac
Greater omental sac
These two sacs communicate with each other through the epiploic foramen of Winslow
What are the embryonic derivatives of the ventral mesentary?
What are the embryonic derivatives of the dorsal mesentary?
Mesentery of small intestine
What are the 4 gut tube derivatives?
What structures make up the foregut? What artery supplies these regions?
1st and 2nd part of duodenum
Supplied by the celiac artery
What structures make up the midgut? What artery supplies these regions?
3rd and 4th part of duodenum
Jujunum and ilium
Cecum and vermiform appendix
Proximal 2/3 of transverse colon
Supplied by the superior mesenteric artery
What structures make up the hindgut? What artery supplies these regions?
Distal 1/3 of transverse colon
Descending and sigmoid colon
Proximal portion of anal canal
Supplied by the inferior mesenteric artery
What are the 2 rotations of the embryonic gut? What are the results?
90 degree logitudinal rotation of foregut towards right side. Brings liver and stomach to the right side and forms greater and lesser omentums
270 degree counterclockwise of midgut frames GI tract by large intestine and brings cecum and appendix to lower right quadrant
What structures are intraperitoneal structures? (10)
duodenum (1st part)
small intestine from duodenal-jujunal flexure to ileocecal junction
Cecum and appendix
What are the primary retroperitoneal structures?
Aorta and inferior vena cava
