Flashcards in Anatomy of Peritoneal Cavity Deck (21):
1

What is the function of mesenteries?

Transmit vessels and nerves, allow mobility

2

What is the nerve supply of the parietal peritoneum?

somatic nerves

3

What is the nerve supply of the visceral peritoneum?

autonomic nerves

4

What viscera are primarily retroperitoneal?

Paired viscera

5

What are the paired viscera?

Kidneys, adrenals, ureters

6

What viscera are secondarily retroperitoneal?

ascending and descending colon, duodenum, pancreas, bile duct

7

What viscera are intraperitoneal?

stomach, jejenum and ileum, ceacum and appendix, transverse colon, sigmoid colon, liver, gall bladder, spleen

8

What is the mesentery?

The mesentery of the jejunum and the ileum

9

What is the path of the mesentery?

Starts at the the DJ flexure and extends obliquely downward to the right and ends at the ileocaecal junction - goes across the 3rd part of the duodenum, the aorta and IVC, the right ureter and right psoas

10

What is the transverse mesocolon?

The mesentery of the transverse colon

11

What is the path of the transverse mesocolon?

Travels across the head and body of the pancreas and the second part of the duodenum

12

What is the sigmoid mesocolon?

The mesentery of the sigmoid colon

13

What is the path of the sigmoid mesocolon?

Inverted v shape over the division of the left common iliac artery

14

What is the omentum?

A double layer of peritoneum that passes from the stomach to other viscera

15

What is the lesser omentum?

A double layer of peritoneum that extends from the lesser curvature of the stomach and the first inch of the duodenum to the visceral surface of the liver

16

What is the epiploic foramen?

The gap at the free edge of the lesser omentum that is the entrance to the lesser sac

17

What are the borders of the epiploic foramen?

Duodenum below, quadrate lobe of the liver above, portal triad in front, IVC behind

18

What is the bare area of the liver?

the area of the liver where the lesser omentum doesn’t quite meet back up before attaching to the diaphragm

19

What is the greater omentum?

A double layer of peritoneum that extends from the greater curvature of the stomach and the first part of the duodenum and drapes down over the front of the abdominal cavity and then reflects back up and adheres to the transverse colon and then attaches to the posterior abdominal wall at the same place as the transverse mesocolon

20

What is the gastro-lienal ligament?

The part of the greater omentum which envelops the spleen before going to the posterior abdominal awl

21

What is the gastro-phrenic ligament?

the part of the greater omentum that attaches directly to the diaphragm
