Lec5AbdominalCavity-Peritoneum & Stomach & Spleen & Liver & Gallbladder & Pancreas Flashcards
What is the upper border of the peritoneum?
thoracic diaphragm
What is the lower border of the peritoneum?
superior pelvic aperture
What are the contents of the peritoneum?
peritoneum=parietal +visceral
abdominal viscera (organs): digestive organs, spleen, kidneys and adrenal (suprarenal) glands
What does the parietal peritoneum line?
abdominal cavity wall
The parietal peritoneum lines the ant abdominal wall and that includes which structures?
transversalis fascia, (extra-peritoneal) fat, mesothelium
The parietal peritoneum lines the post abdominal wall and that includes which structures?
muscles (all 4), fascia (CT), mesothelium
What exactly is the peritoneal cavity?
The space between the parietal and visceral peritoneum
What is the visceral peritoneum?
covers abdominal organs
What does the visceral peritoneum form and what does it allow for?
Forms mesenteries+ omenta + ligaments (all have a double layer)
The thin vascular membrane allows for IP injection of drugs
What two spaces is the peritoneal cavity divided into?
Greater sac and lesser sac
What is the greater sac?
major part of the peritoneal cavity
What is the lesser sac and its location?
omental bursa
post to stomach and lesser omentum
extends superior and inferior recesses
What is the opening between the greater and lesser sac called? and where is it located?
epiploic (omental) foramen/ foramen of winslow
posterior to the lesser omentum (hepatoduodenal ligament)
What is the omentum/omenta(singular)?
double layered folds of visceral peritoneum
What is the greater omentum?
connects stomach to transverse colon.
derived from dorsal mesentery
mostly fatty tissue
What is the lesser omentum
connects stomach + duodenum to liver.
derived from ventral mesentery
What 2 ligaments are in the lesser omentum?
hepatogastric ligament
hepatoduodenal ligament
What is the arterial supply of the foregut?
abdominal aorta—CELIAC TRUNK— (left gastric a, splenic a, common hepatic a to right gastric a)
Where does the foregut and midgut sympathetic innervation come from?
Thoracic splanchnics
Where does the foregut and midgut parasympathetic innervation come from?
vagus nerve
What are the intraperitoneal organs (covered on all sides) of the abdominal cavity?
Splenda Sweetener Doesn’t Take Like Sugar
Spleen
Small Intestine (jejunum +ileum)
Duodenum (superior part)
Transverse Colon
Liver
Stomach
What are the retroperitoneal organs (covered on anterior side) of the abdominal cavity?
kidneys +suprarenal (adrenal) glands
What are the secondary retroperitoneal organs of the abdominal cavity?
A Dynamic Duo Pair
Ascending colon
Descending colon
Duodenum (descending +horizontal +ascending parts)
Pancreas
What are the structures of the stomach?
cardia: connects stomach to esophagus
Fundus: 1st segment
Body: 2nd segment
Pylorus (antrum)=3rd segment
Pyloric sphincter: connects to duodenum
Gastric Rugae:internal folding of a stomach (enables stomach to expand
Does the kidney +suprarenal (adrenal) glands have mesentary?
NO, bc its a retroperitoneal organ
