Peritoneum & Peritoneal Cavity
Cards in this deck (23)
- 1What structures does the peritoneum form?Mesentery
Omenta - Greater & Lesser
Ligaments - peritoneal folds - 2Location of the lesser sacPosterior to the stomach & lesser omentum
- 3Location of the greater sacBetween the diaphragm & the pelvis
- 4Epiploic foramen + its boundariesConduit for communication between the greater & lesser sac
Boundaries = Hepatoduodenal lig., IVC, Caudate lobe of liver & 1st part of the duodenum - 5Pringles ManoeuvreA surgical manoeuvre which compresses, via the epiploic foramen, the hepatic artery proper & hepatic portal vein to control bleeding
- 6From where are the omenta derived?Lesser omentum = Ventral mesentery
Greater omentum = Dorsal mesentery - 7State the extent of the lesser & greater omentaLesser
- From the lesser curvature & 1st part of the duodenum to the inferior border of the liver
- Divided into hepatoduodenal & hepatogastric regions
Greater
- From the greater curvature & 1st part of the duodenum then hangs over the abdomen anterior to the intestines - 8Hepatoduodenal lig.Free edge of the lesser omentum
Contains the portal triad:
- Hepatic artery proper
- Hepatic portal vein
- Common bile duct - 9What is mesentery?Tissue formed by a double layer of parietal peritoneum, derived from the dorsal mesentery, which attaches the abdominal organs to the posterior abdominal wall & acts as a conduit for blood vessels, lymphatics & nerves
- 10What is THE mesentery? Describe its course & contentsMesentery of the small intestine, attaching the jejunum & ileum to the posterior abdominal wall
Course = Left of L2 to the Right sacro-iliac joint - crossing the 3rd part of the duodenum, aorta, IVC, right gonadal vessels & right ureter
Contents = Superior mesenteric vessels, nerves & lymphatics - 11Describe the course & contents of the sigmoid mesocolonRoot in the left iliac fossa then crosses the bifurcation of the left common iliac vessels & left ureter
Transmits the sigmoid branches of the inferior mesenteric vessels + nerves & lymphatics - 12Describe the course & contents of the transverse mesocolonRoot is just inferior to the pancreas
Contains branches of the middle colic vessels - 13State the contents of the supra colic & infra colic compartmentsSupra colic: Duodenum, Gallbladder, Stomach, Spleen & Liver
Infra colic: Duodenum, Jejunum, Ileum, Ascending & Descending colon - 14Para colic gutters: 1. Location 2. Function1. Between the lateral aspect of the ascending or descending colon & the posterior abdominal wall
2. Allows communication between the supra colic & infra colic compartments - 15Name & State the location of the various peritoneal pouches, recesses & gutters1. Hepato-renal recess / Morrisons pouch
- between the liver, right kidney & right supra-renal gland
2. Recto-vesical pouch
- between the rectum & urinary bladder in males
3. Recto-uterine pouch
- between the rectum & uterus in females
4. Vesico-uterine pouch
- between the urinary bladder & uterus in females - 16Where can fluid collect when in the recumbent position?Morrisons pouch
- 17Name & state the origin of the peritoneal folds1.
2.
3. - 18Between the folds & lateral to the umbilical fold whats recesses exist?1. Supra-vesical fossa
2. Medial umbilical fossa
3. Lateral umbilical fossa - 19Explain the term secondary retroperitonealInitially intraperitoenal but moves retroperitoneally during embryogenesis & losses its mesentery
- 20Name the primary retroperitoneal organsAorta
IVC
Abdominal oesophagus
Proximal 2/3 rectum
Supra-Renal glands & Kidneys
Bladder & Ureters - 21Name the secondary retroperitoneal organsPancreas
Duodenum ( - 1st part)
Ascending & Descending colon - 22Describe the nerve supply of the parietal peritoneumAnterior abdominal wall - T7-L1
Diaphragmatic peritoneum - Phrenic n. (C3-5)
Pelvic peritoneum - Obturator n. (L2-4) - 23Describe the nerve supply of the visceral peritoneumAutonomic Afferent Nerves
- poor localisation to pain as it is only sensitive to stretch & tear
