1

 What does the term intraperitoneal mean? 

  • organs are completely covered with visceral peritoneum 
  • organs are attached to each other or to the abdominal wall by a double fold of peritoneum 

2

What is the abdominal cavity bounded by?

  • Diaphragm 

  • Anterolateral abdominal wall – external and internal oblique, transversus abdominis and rectus abdominis and pyramidalis

  • Posterior abdominal wall - vertebral column, quadratus lumborum, PSOAS major and iliacus 

  • Pelvic inlet

3

What is the pelvic inlet bounded by?

  • Posterior : sacral promontory 

  • Arcuate line

  • Pectineal line and pubic crest

  • Pubic symphysis is a secondary cartilaginous joint

4

What is everything below the pelvic inlet called and what structures are included?

  • lesser pelvis

  • (reproductive organs, terminal end of alimentary canal and bladder) 

5

What 2 structures make up the abdominal cavity?

  • greater pelvis and the abdomen proper

6

What is peritoneum?

  • one continuous layer that is wrapped around all of the organs in the abdominal cavity 

7

What is the difference between visceral and parietal peritoneum?

  • Anything that touches an organ is known as visceral peritoneum and anything that is not touching an organ is called parietal peritoneum 

8

What is peritoneal fluid made of?

  • water, electrolytes,interstitial fluid, leukocytes and antibodies 

9

Why is the peritoneal cavity open in females?

  • space between the fimbriae and the ovary means that the peritoneal cavity in females is open  

10

How does the peritoneum communicate with the exterior in females?

  •  via the vagina, uterus and uterine tubes in females

11

What does parietal peritoneum line?

  • wall of the abdominal and pelvic cavities

12

What is the parietal peritoneum sensitive to?

  • pain
  • temperature
  • touch
  • pressure

13

What is the parietal peritoneum innervated by?

  • T7-L1

14

What does the visceral peritoneum line?

  • the abdominal and pelvic organs/viscera

15

What is the visceral peritoneum sensitive to?

  • stretch
  • tearing

16

What is the visceral peritoneum innervated by?

  • afferent nerves that travel with autonomic supply to viscera it covers

17

18

What does over distension of the visceral peritoneum lead to?

  • pain

19

Where is the peritoneal cavity?

  • The space between the parietal and visceral peritoneum

20

What is contained within the peritoneal cavity?

  • peritoneal fluid

21

What is the greater sac?

  • space of the peritoneal cavity, posterior to the anterolateral abdominal wall

22

Why is pain from the abdominal region poorly localized?

  • Dermatomes share a convergent spinal root with the autonomic nerve which supply that particular organ

23

What is the foregut region supplied by?

  • greater splanchnic nerves
  • T5-T9

24

What is the midgut supplied by?

  • lesser splanchnic nerves
  • T9-T11

25

What is the hindgut supplied by?

  • lumbar splanchnic nerves
  • L1-L2

26

What is the lesser omentum and what does it do?

  • double fold of peritoneum that attaches the liver to the lesser curvature of the stomach (hepatogastric ligament) and to the first part of the duodenum (hepatoduodenal ligament)

27

What is the lesser omentum derived from?

  • ventral mesogastrium 

28

What are the 3 things that a double fold of peritoneum can be called?

  • mesentery, ligament or an omentum

29

What structures are located within the free edge of the lesser omentum?

  • hepatic artery
  • the portal vein
  •  the common bile duct
  •  lymph glands
  •  lymph vessels
  • nerves

30

Where is the lesser sac and what is it continuous with?

  • The lesser sac lies posterior to the stomach and is continuous with the greater sac through the epiploic foramen.
