Peritoneum Flashcards

1
Q

What are the X3 primitive subdivisions of the alimentary tract?

What do each of these equate to in the fully developed alimentary tract?

A

Foregut = tract up to the proximal duodenum

Midgut = proximal duodenum —> 2/3 along the transverse colon

Hindgut = final 1/3 transverse colon —> rectum

Q

What is the blood supply to the foregut structures?

Where does this vessel arise from?

A

Via the celiac trunk, a branch of the abdominal aorta at the level of T12.

Q

What is the difference between primary and secondary retro-peritoneal organs?

A

Primary = developed without a mesentary

Secondary = developed with a mesentary which was reabsorbed into the parietal peritoneum

Q

In development, what caused organs such as the pancreas and duodenum to become retro-peritoneal?

A

The enlarging liver, forcing them backwards to become retro-peritoneal.

Q

In development, how were the visceral peritoneum and the mesenteries formed?

A

The peritoneum from each side of the body merged in the midline to form the visceral peritoneum and the mesenteries.

Q

What ligaments connects the stomach to the spleen?

A

The gastrosplenic ligament.

18
Q

What ligament connects the spleen to the kidneys?

A

The splenorenal ligaments.

19
Q

How does the stomach move as it is forming?

A

It rotates anti-clockwise and moves upwards, also growing faster on one side to creates a greater and lesser curvature.

20
Q

What does the rotation of the stomach do to its dorsal mesogastrium and what X2 structures does this form?

A

The anti-clockwise stomach rotation pulse the dorsal mesogastrium to the left side of the body, creating a peritoneal subdivision called the OMENTAL BURSA (lesser sac).

The dorsal mesogastrium continues to grow caudally to form the GREATER OMENTUM.

21
Q

How many layers is the greater omentum formed of?

A

X4 layers, but the inner two fuse.

22
Q

What is the role of the greater omentum?

A

It plays a part it localising infection, sticking to it and aiding the delivery of lymphocytes via omental arteries (branches of the gastroepiploic arteries which follow the greater curvature of the stomach).

23
Q

What travels in the ligaments?

A

Blood vessels/lymphatics.

24
Q

What is the lesser sac?

How can it be accessed?

A

It is the space behind the stomach, accessed underneath the lesser omentum via the EPIPLOIC FORAMEN.

25
Q

Which parts of the small intestine are intra-peritoneal?

Which mesentery is this?

A

The jejunum and ileum.

THE mesentery!

26
Q

Which parts of the large intestine are intra-peritoneal?

What are their respective mesenteries called?

A

The transverse colon and sigmoid colon.

They are called MESOCOLONS (transverse mesocolon & sigmoid mesocolon).

27
Q

What is the greater sac split into by the transverse mesocolon?

What spaces link these two together?

A

It splits the greater sac into supra- and infra-colic complements.

These are linked by PARACOLIC GUTTERS.

28
Q

How many pelvic peritoneal folds do males have?

What are they called?

A

X1 = rectovescicle pouch.

“Vesico” prefix = bladder

29
Q

How many pelvic peritoneal folds do females have?

What are they called?

A

X2:

= vesicouterine pouch
= rectouterine pouch

(“Vesico” prefix = bladder)

30
Q

What ligament connects the liver to the anterior abdominal wall?

A

The falciform ligament.
