Anatomy

Surgical Anatomy

• The peritoneum forms the lining of the abdominal cavity & viscera

• Single layer mesothelial cells on a layer of fibroepithelial tissue.

• Few ml of pale yellow fluid lubricates peritoneal surface.

• Visceral & parietal peritoneum

• Greater & lessor sac.

• Visceral peritoneum:

  • Poor nerve supply (ANS)
  • Irritation & inflammation:
    • Pain poorly localized
    • Dull & felt in midline

• Parietal peritoneum:

  • Somatic nerve
  • Irritation & inflammation:
    • Accurately localized
    • Sharp

• Retroperitoneal space
