Mesentery

what does ens control

controls the 2 plexi

the periotoneum of the abdominopelvic cavity consists of?

consists of parietal and visceral membrane

what does ens control

controls the 2 plexi

the periotoneum of the abdominopelvic cavity consists of?

consists of parietal and visceral membrane

what does parietal peritonuem line?

lines inner surface of abdominal wall

what does visceral periotoneum cover?

covers surface of internal organs

what is the peritoneal cavity

peritoneal cavity is a space between parietal + visceral peritoneum containing serous fluid

function of serous fluid produced by periotoneum?

lubricates abdominal organs to reduce friction

main function of serous membranes of abdominal cavity

protect organs that r always moving > when peristalsing or segmenting = movement of organs rub against one another = need fluid to not allow irritation

laparoscopic

fill peritoneal cavity w/ gas = elevates up

parietal periotoneal membrane

adheared to abdominal cavity(lines whole inside of abdominal cavity), lateral walls, back of abdominal cavity

if an organ is encompassed by visceral membrane… what is it refered to?

intraperitoneal

intraperitoneal organs within abdomen are surrounded by?

visceral peritoneum

intraperitoneal organs

stomach, most of small intestine, transverse colon, sigmoid colon, and liver

retroperitoneal organs lie where?

lie outside the parietal peritoneum directly against posterior abdominal wall

retroperitoneal organs are assocaited with?

digestive, urinary, cardiovascular system

mnemonic for retroperitoneal organs

SAD PUCKER
S= suprarenal glands(adrenal glands), A = Aorta + inferior vena cava, D = Duodenum(most of), P = pancreas, U = Urinary bladder + uterus, C = colon(ascending + descending), K = kidneys, E = esophagus(abdominal portion), R = rectum

mesentery (peritoneal folds)

double folds of visceral peritoneal membrane that extends from back wall of abdominal cavity

function of mesentery (peritoneal folds)

structural integrity + safe passage of vessels (vascular supply for intraperitoneal organs)

5 mesentery structures

greater omentum, lesser omentum, falciform ligament, mesentery proper, mesocolon

greater omentum

extends inferiroly like apron from greater curvature of stomach
convers most of abdominal organs + back to transverse colon

wwhy is greater omentum called fatty apron? + what is it considered?

accumulates large amounts of adipose CT
considered organ

lesser omentum

connects lesser curvature of stomach to liver (connects stomach to liver)

falciform ligament

flat + thin + cresent shaped periotneal fold that attaches the LIVER to anterior abdominal wall

mesentary proper

fan shaped fold of peritoneum that binds jejunum and ileum to posterior abdominal wall

mesocolon

fold of peritoneum that attaches the transverse colon + sigmoid to the posterior abdominal wall

what does mesocolon provide

provides structural integrity to transverse colon + safe passageway for vessels

function of lesser omentum

structural integrity = make sure stomach + liver dont pull away from each other
provides safe passageway for vessels

what does mesentery proper contain?

has blood vessels that give oxygen to cells to intestines + pick up absorbed material

chrons disease

irritation of small intestine > mesenteric fold walsk over + grabs it to protect inflammed area

when you filp greater omentum what does it expose?

expose jejunum + ileum

what does lesser omentum wrap?

wraps around liver > come back together on diaphragm to create falciform ligament

what does falciform ligament not contain?

no vessels

proper mesentery wraps around?

wraps around all segments of distal small intestine + adhere them to posterior abdominal wall

Complete the > facliform ligament is @….

falciform ligament is @ liver > lesser omentum liver to stomach > greater omentum sotmach to transverse colon > mesocolon
