Peritoneum and peritoneal cavity

  1. 1. The abdominal cavity, the peritoneum& the peritoneal cavity By Dr. Noura El Tahawy Faculty of Medicine El Minia University
  2. 2. • Superficial view of• the abdominal• organs
  3. 3. Peritoneum
  4. 4. • Sagittal section through the abdominopelvic cavity
  5. 5. Abdominal cavity proper• The larger part of the abdominopelvic cavity• BOUNDARIES• Superiorly: diaphragm• Inferiorly: Pelvic inlet• A large part is under the cover of the osteocartilaginous thoracic cage• Walls are lined by the parietal peritoneum
  6. 6. • Thin transparent serous membrane that consists of 2 layers:• 1. PARIETAL PERITONEUM – lines the abdominal cavity• 2. VISCERAL PERITONEUM – invests the abdominal viscera
  7. 7. • Composed of a single layer of squamous epithelial cells (mesothelium)• The 2 layers are separated by a capillary film of peritoneal fluid.

  9. 9. PERITONEAL DERIVATIVES: ExamplesPeritoneal Derivative From ToLigaments Solid viscera Abdominal wall Falciform ligament liver Diaphragm and anterior abdominal wall
  10. 10. Peritoneal cavity
  11. 11. • DEFINITION• The potential space between the parietal and visceral layers of the peritoneum• MALES: closed cavity• FEMALES: (+) communication with the exterior through the reproductive tract (fallopian tubes, uterus, vagina)
  12. 12. Divisions of the peritoneal cavity • As the fetal organs assume their adult positions, the parietal cavity is divided into the 2 peritoneal sacs: 1. the greater sac 2. the lesser sac (omental bursa)
  13. 13. Peritoneal cavity• GREATER SAC • LESSER SAC• Main compartment of • Smaller the peritoneal cavity• Extends from the • Lies behind the diaphragm into the stomach pelvis The communication between the greater sac and the lesser sac is the EPIPLOIC FORAMEN

PERITONEAL DERIVATIVES: ExamplesPeritoneal Derivative From ToOmentum Stomach Another viscus Greater omentum Greater curvature Transverse colon Lesser omentum Lesser curvature Undersurface of the liver Hepatogastric ligament Hepatoduodenal ligament Gastrosplenic Stomach Hilum of the spleen omentum (ligament)
