peritoneum and peritoneal cavity

what is the parietal peritoneum

portion of serous membrane that lines the inside surface of the body wall

what is the visceral peritoneum

portion of serous membrane that folds back to cover the surface of internal organs

what is the peritoneal cavity

space where the peritoneal layers that afce eachother secrete a lubricating serous fluid

what does intraperitoneal mean

organs that are completely surrounded by visceral peritoneum

what does retroperitoneal mean

organs are covered by peritoneum on their anterolateral surfaces only

what are mesenteries

folds of peritoneum that support and stabilize the intraperitoneal GI tract organs

what are between the folds of peritoneum in mesenteries

blood vessels, lympathethic vessels, and nerves that supply the digestive organs

what is the greater omentum

extends inferiorly like an apron from the greater curvature of the stomach and covers most of the abdominal organs

what is the lesser omentum

connect the lesser curvature of the stomach and the proximal end of the duodenum to the liver

what can the lesser omentum be divided into

hepatogastric ligament and hepatoduodenal ligament

what is the hepatogastric ligament

connect liver to stomach

what is hepatoduodenal ligament

connect liver to duodenum

what is the mesentery proper

fan shaped fold of peritoneum that suspends most of the small intestine from the internal surface of the posterior abdominal wall

what is the mesocolon

peritoneal fold that attaches parts of the large intestine to the internal surface of the posterior abdominal wall

what is a peritoneal ligament

peritoneal fold that attaches one organ to another organ

what are some examples of peritoneal ligaments

coronary, falciform, and lienorenal ligament

what is the coronary ligament

peritoneal fold attaching the superior surface of the liver to the diaphragm at the margins of the bare are of the liver

what is the falciform ligament

peritoneal fold that attaches the liver to the anterior internal abdominal wall

what is the lienorenal ligament

a fold of peritoneum between the spleen and the kidney

what is the gastrosplenic ligament

peritoneal fold connecting greater curvature of stomach to splenic hilum

what is the gastrophrenic ligament

peritoneal fold that connects the posterior surface of the gastric fundus to the underside of the diaphragm near the left crus

what is the gastrocolic ligament

a significant fatty four layered membrane portion of the greater omentum connecting the greater curvature of the stomach to the transverse colon

what are peritoneal folds

double layered reflections of peritoneum that connect abdominal porgans to each other or to abdominal wall

what is the lateral umbilical fold

paired ridge of parietal peritoneum on the inner anterior abdominal wall created by the underlying epigastric vessels

what is the medial umbilical fold

bilateral paired folds located lateral the the median umbilical fold

what is the median umbilical fold

single fold located in the exact midline of the inner abdominal wall

what is a remnant of the urachus

median umbilical ligament

what are some intraperitoneal organs

stomach, jejunum, ileum, cecum, appendix, transverse and sigmoid colon

what are some retroperitoneal organs

pancreas, ascending and descending colon, rectum
