  1. Greater Sac
    long, thin area, from diaphragm to pelvis

    [peritoneal cavity]
  2. Lesser Sac
    peritoneal cavity located behind the stomach
  3. Superior boundary of the lesser Sac
    the diaphragm
  4. Inferior Boundary of the lesser Sac
    transverse colon and transverse mesocolon
  5. left (lateral) boundary to the lesser sac
    gastrolineal ligament, lineorenel ligament, and spleen
  6. Right (medial) Border of the lesser sac
    epiploic foramen (of Winslow)
  7. Epiploic foramen of Winslow:
    real opening to the lesser sac

    [the right-medial border of the lesser sac]
  8. anterior boundary of epiploic foramen of Winslow
    hepatoduodenal ligament (part of lesser omentum), contains: hepatic artery, common bile duct, and portal vein
  9. Posterior Boundary of Epiploic foramen of Winslow
    Inferior Vena Cava
  10. Superior Border of the Epiploic Foramen of Winslow
    caudate lobe of the liver
  11. Inferior Border of Epiploic foramen of Winslow
    • First part of the Duodenum
    • & mesocolon
  12. Mesenteries:
    two layered fold of visceral peritoneum that connects mobile viscera/ organs to the posterior abdominal wall
  13. Two Origin Locations for Mesenteries
    1) intraperitoneal

    2) Retroperitoneal
  14. Intraperitoneal:
    Organs suspended by mesentery into cavity
  15. Retroperitoneal:
    organs lacking a mesentery and fused to body wall
  16. Examples of Mesenteries:
    Transverse Mesocolon

    sigmoid mesocolon
  17. Omentum:
    two layered fold of visceral peritoneum that attaches stomach to another organ
  18. Two forms of Omentums:
    1) Greater Omentum

    2) Lesser Omentum
  19. Greater Omentum:
    connects the greater curvature of the stomach with anterior body wall

    *hangs down in cavity like an apron over viscera
  20. What is the greater omentum composed of?
    1) gastrocolic ligament

    2) gastrolineal ligament

    3) lienorenal ligament

    4) omental apron
  21. Lesser Omentum:
    connects the lesser curvature of the stomach with the liver
  22. what is the lesser omentum composed of?
    1) falciform ligament

    • 2) superior hepatic ligaments
    • (coronary and triangular ligaments)

    3) hepatoduodenal ligaments

    4) hepatogastric ligament
  23. Periotoneal Ligaments
    two layered fold of visceral peritoneum that attach the lesser mobile viscera to abdominal walls
  24. Examples of Peritoneal Ligaments
    1) falciform ligament

    2) hepatogastric ligament
  25. Falciform ligament
    attaches liver and the anterior abdominal wall
  26. hepatogastric ligament
    Between the liver and the lesser curvature of the stomach
  27. Two layers of Peritoneum in the Abdomen
    1) visceral peritoneum

    2) parietal peritoneum
  28. Superior Boundary for the Abdominal Wall
    Diaphragm
  29. Inferior Boundary of the Abdominal Wall
    continuous with the pelvic cavity
  30. Anterior Boundary of the abdominal wall
    lower part of thoracic cage; and abdominal muscles
  31. Posterior Boundary of Abdominal Wall
    L1-L5; 12th Rib, pelivs and muscles
  32. Lateral Boundary of the Abdominal Wall
    Thoracic Wall and Abdominal Muscles
  33. Umbilicus
    Belly Button, located @ T10 Dermatome, is located in the midsaggital plane
  34. McBurney's Point
    go to anterior superior iliac spine, move 1/3 laterally

    *marking of the appendix [on the R side]

    * could also be the place of an inguinal hernia or an ovarian sist
  35. Branches of the Lumbar Plexus
    1) iliohypogastric Nerves

    2) ilioinguinal nerves

    3) lateral cutaneous nerve of the thigh

    4) femoral nerve

    5) obturator nerve

    6) genitofemoral nerve
  36. iliohypogastric nerve
    (where does it originate and what does it supply)
    where: L1

    supplies: skin of lower anterior abdominal wall
  37. ilioinguinal nerve

    (where does it originate and what does it supply)
    where: L1

    supplies: skin of the groin/ and scrotum/ labia majora
  38. lateral cutaneous nerve of the thigh

    (where does it originate and what does it supply)
    where: L2, L3

    supply: skin over the lateral surface of the thigh
  39. femoral nerve

    (where does it originate and what does it supply)
    where: L2 - L4

    supply: iliacus muscle, and structures of the thigh/ calf
  40. obturator nerve:

    (where does it originate and what does it supply)
    where: L2 - L4

    supplies: structures in the parietal peritoneum on lateral wall of pelvis plus structures in the thigh
  41. Genitofemoral Nerves:

    (where does it originate and what does it supply)
    where: L1, L2

    supply: divides into genital branch

    and divides into femoral branch
  42. Genital branch of the genitofemoral nerves supplies what?

    formed in the psoas muscle from the ventral rami of L1 - L4
  45. The superficial nerve supply for the posterior abdominal wall is also referred to as:
    dorsal rami of lumbar spinal nerves
