7

What is preset in the peritoneal cavity

Peritoneal fluid

8

Which layer of the peritoneum is more sensitive to pressure, pain, heat & cold

Parietal

9

What are the attachments of the greater omentum

Greater curvature of the stomach to the transverse colon

10

What are the attachments of the lesser omentum

Liver to stomach (heptogastric)

11

The parietal peritoneum lining is innervated by

The lower 6 thoracic nerves and L1- pain is somatic

12

The visceral peritoneum is innervated by

autonomic nerves- pain is dull and often referred and poor localised

T12

19

What are the 3 main branches of the abdominal aorta which supplies blood to the gut tube

Celiac, inferior mesenteric, superior mesenteric

20

How is the inferior vena cava formed in the abdomen

Distal oesophagus
Rectal
Paraumbilical and small epigastric
Colic (portal) and retroperitoneal

29

What is the clinical significance of these portocaval anastomoses
