Q

What are fossae or recesses?

A

depressions between folds

17
Q

Structures coursing through the extra peritoneal tissue form elevations on the interior abdominal wall called what?

A

peritoneal (umbilical) folds

18
Q

A

medial: 2
lateral: 2

19
Q

Median umbilical fold is formed by what?

A

urachus

20
Q

The medial umbilical folds are formed by what?

medial umbilical ligaments

21

26
Q

What is the greater sac of the peritoneal cavity?

A

most of the “potential” space within the abdomen

27
Q

Recesses and fossae of the peritoneal cavity are clinically important because…?

A

abscesses may develop and excess fluid will pool there

28
Q

THE mesentary

29
Q

phrenicocolic

30
Q

A

posterior and inferior to the stomach

31
Q

How do the greater and lesser sac communicate?

A

through the epiploic foramen (of Winslow)

32
Q

Where is the superior recess located?

A

posterior to the liver

33
Q

Where is the inferior recess located?

A

potential space between the 2 layers of the gastrocolic ligament

34
Q

Where is the splenic recess found?

A

posterior to and left of the stomach
