Stomach, duodenum, celiac trunk Flashcards
Explain intraperitoneal organ
- surrounded by the visceral peritoneum
- attached to the wall by a mesentery
- suspended within peritoneal cavity
- mobile
Explain retroperitoneal organ
- incompletely surrounded by peritoneum
- Does not have a mesentery
- fixed to the posterior abdominal wall
Mesentery
allows vesicles to enter the organ and provide blood supply for the wall
have nerves to innervate wall
has lymphatic vessels to drain from organ
also contains adipose tissue
Is double layer of peritoneum
What is the parietal peritoneum attached to?
Abdominal walls
What is the visceral peritoneum found on?
Organs
What is peritoneal cavity?
space between the parietal peritoneum and visceral peritoneum
are intraperitoneal organs inside the peritoneal cavity?
NO!!!
what dose the greater omentum anchor?
greater curvature of the stomach, ascending, transverse and descending colon, draped over duodenum and jejunum and some of ileum
what is the mesentery?
double fold of peritoneum that attaches organs to abdominal wall
what is a ligament?
double fold of peritoneum that attaches organs together
Are the sigmoid colon and transverse colon intra peritoneal?
Yes
What makes up the greater omenum?
Gastrophrenic ligament
Gastrosplenic ligament
Gastrocolic ligament
Where will fluid accumulate when a person has ascites and is laying supine?
Morrison’s pouch
peritoneal space
region of the body in which two surface membranes adjoin, separated in healthy individuals by only a small amount of fluid lubrication
What makes up the lesser omentum?
Hepatoduodenal ligament
hepatogastric ligament
hepatoesophageal ligament
What does the pylorus of the stomach do?
Controls the contents that flow into the duodenmun
List some organs that are retro peratoniel
pancreas, IVC, aorta, kidneys, ascending colon, descending colon, rectum, duodenum
list some organs that are intra peratoniel
stomach, liver, spleen, small intestines,
What is the lesser sac between?
stomach/ lesser omentum to pancreas
What does the heptoduodenal ligament contain?
Common bile duct, proper hepatic artery, portal vein
What foramen are you able to stick your finger into?
Foramen of Winslow that goes into omental bursa
Explain the structure of duodenum
Superior part
descending part
horizontal part
ascending part
What is the only part of the duodenum that has a mesentery?
Superior part
What is the part of the duodenum that has a division between foregut and midgut
Descending part
What is the junction of the duodenum and jujunum?
Duodenaljejunal flexure (ligament of Treitz)
What are the main branches off of the celiac trunk?
Left gastric artery
splenic artery
common hepatic artery
what arteries supply the lesser curvature of the stomach?
Left gastric artery
right gastric artery
What branches off of the splenic artery?
Left gastro- omental artery
short gastric arteries
What branches off of the common hepatic artery?
Gastroduodenal artery
right gastric artery
When does the common heptatic artery merge into?
Proper hepatic artery
When does the proper hepatic artery arise (in name)
after the gastroduodenal artery is branched off of the common hepatic artery
what branches off of the proper heptatic artery?
Right and left hepatic arteries
What branches off of the right heptatic artery?
Cystic artery
What does the gastroduodenal artery branch into?
Right gastro- omental artery
superior pancreaticoduodenal artery
What branches off of the left gastric arteries?
Esophageal branch
What can occur with a duodenal ulcer?
Can eat through the wall of duodenum and then eat through gastroduodenal artery
bleeds though the upper duodenum and patient comes in throwing up blood
Where is the spleen located
9th - 11th ribs on left side
lies between the stomach and the rib cage
achalasia
Nerve problem
Lower esophageal sphincter is contracting all of the time
end up with a dilated esophagus
Scleroderma
lower esophageal sphincter is destroyed
any contents in the stomach are free to reflux back into the esophagus
Where is the cardia of the stomach located?
surrounding the esophageal orifice
Where is the pylorus of the stomach?
Near the gastroduodenal junction
What do the rugae of the stomach do?
increase surface area
allow stomach to expand if needed
