Abdominal Cavity Flashcards
____________ is a tissue that extends from greater curvature of the stomach to the transverse colon
Greater Omentum
The Right (hepatic) colic flexure separates the ascending colon and the ____________
Transverse colon
The left (splenic) colic flexure separates the transverse colon and the ____________________
Descending colon
The caecum is the pouch where the ileum meets the ____________ and ends in the _____________
- Colon
- Appendix
The ____________ is the muscular band of the colon and ____________
- Taenia Coli
- Cecum
________ are little globules of fat tha hang on the large intestine
Epiploic appendices
What structures are essential for how the gut sits in the cavity?
Dorsal and Ventral mesentary
What will become most of the mesentary in the gut cavity in and adult and what will mostly disappear and decompose?
- Dorsal
- Ventral
What mesentary holds organs to the posterior body wall?
Dorsal
mesenteric relations - intraperitoneal: some organs can move around because they are only attached by dorsal mesentery ie stomach
Secondarily retroperitoneal organs are attached by single piece of mesentery but during development, get _________ _________ the body wall
Trapped behind
mesenteric relations - **secondarily retroperitoneal **(behind peritoneum): organs do not move/get “stuck” behind peritoneum ie ascending colon
The only organs that are primarily retroperitoneal are the (name the 3 structures):
- Esophagus
- Rectum
- Anus
When it comes to mesenteric relations, all the organs in the middle started out as free, ________ structures, and only some organs became ____________ due to some motion during development and it got sealed off.
- Mobile/moving
- Secondarily Retroperitoneal
mesenteric relations:
1. Intraperitoneal = moveable and mobile
2. Secondarily retroperitoneal = once mobile, but are now trapped behind layer of mesentery
3. Primarily retroperitoneal = developed behind mesentery and never came back out
The secondary retroperitoneal structures are the (think mneumonic!):
- Pancreas
- Colon (ascending and descending)
- Duodenum
The ________ are an embryologial concept describing the 3 divisions by which the gut develops. They are the:
- Gut divisions
- Foregut, Midgut, Hindgut
The Foregut is composed of initial digestive organs and ___________
Glandular organs
Most of intestine is in what gut division?
Midgut
The last part of the intestine is found in what gut divison?
Hindgut
What are the 3 arteries are part of the gut divisions and come off the ____________
- Celiac trunk
- Superior mesenteric
- Inferior mesenteric
- Aorta
What is the artery that supplies the foregut?
Celiac trunk
What are the three branches of the celiac trunk?
- Left gastric artery
- Splenic artery
- Common hepatic artery
The left gastric artery is a branch of of the ________ and supplies the ____________
- Celiac Trunk
- Lesser curvature of the stomach
The splenic artery gives of the right and left ________-________ arteries
- Gastro-omental
The common hepatic artery gives off the right and left ________________ before becoming the proper hepatic artery and anastomose on the ____________ curvature of the stomach
- Gastric
- Lesser
also gives off gastroduodenal
The common hepatic artery gives off the gastroduodenal artery that branches into (right/left) ________ and will anastomose with the (right/left) ________ from the splenic artery
- Right
- Gastro-omental
- Left
- Gastro-omental
The proper hepatic artery gives off the right and left ____________ artery and the right gives off the ________ artery which goes to the gallbladder.
- Hepatic
- Cystic
The superior pancreaticduodenal artery comes off what trunk?
Celiac
The pancreas has collateral circulation from the ____________ and ________________ artery
- Celiac trunk
- Superior mesenteric
The splenic artery goes through the pancreas and gives off the ____________ and ____________ ________ artery
- Dorsal
- Greater
- Pancreatic
What artery is important for providing collateral circulation to the entire colon?
Marginal Artery
The iliocolic artery provides blood to the ________ gut division and is the junction of the ________ and _______
- Midgut
- Ileum
- Colon
The inferior panccreaticduodenal artery is a branch of the ____________ artery and provides blood to the ________ gut divison
- Superior mesenteric
- Midgut
The ________ meaning “straight vessels” come off what artery and thus, provide blood to the ____________ gut division
- Vasa rectae
- Marginal
- Midgut
The ________ meaning “loops” are important arteries for distinguishing between the jejunum and ileum and thus, are part of the _________ gut division
- Arcades
- Midgut
