Q

An organ is said to be intraperitoneal when it is almost totally covered with?

A

Visceral peritoneum

18
Q

True or false.

The stomach, jejunum, ileum, and spleen are good examples of intraperitoneal organs because they are almost totally covered with visceral peritoneum.

A

True

19
Q

Lie behind the peritoneum and are only partially covered with visceral peritoneum.

A

Retroperitoneal organs

20
Q

True or false.

The pancreas, ascending and descending parts of the column are examples of retroperitoneal organs.

A

True

21
Q

True or false.

No organ, however, is actually within the peritoneal cavity

A

True

22
Q

An intraperitoneal organ, such as the stomach, appears to be surrounded by the peritoneal cavity but it is covered with visceral peritoneum and is attached to other organs by?

A

Omenta

23
Q

Are two layered folds of peritoneum that connects solid viscera to the abdominal walls.

A

Peritoneal ligaments

24
Q

Like in peritoneal ligaments, the liver for example, disconnected to the diaphragm by the?

A
  • Falciform ligament
  • Coronary ligament
  • Right and Left triangular ligaments
25
Q

Are two layered folds of peritoneum that connect the stomach to another viscus.

A

Omenta

26
Q

Connect the greater curvature of the stomach to the transverse colon.

A

Greater omentum

27
Q

It hangs down like an apron in front of the coils of the small intestine and is folded back on itself to be attached to the transverse colon.

A

Greater omentum

28
Q

Suspends the lesser curvature of the stomach from the fissure of the ligamentum venosum and the porta hepatis on the under surface of the liver.

A

Lesser omentum

29
Q

Connects the stomach to the helium of the spleen

A

Gastroplenic omentum (ligament)

30
Q
  • Are two layered folds of peritoneum connecting parts of the intestines to the posterior abdominal wall.
  • For example the mesentery of the small intestine that transfers mesocolon and the sigmoid mesocolon.
A

Mesenteries

31
Q

Is sensitive to pain temperature touch and pressure.

A

Parietal peritoneum

32
Q

Lining the interior abdominal wall is supplied by the lower six thoracic and first lumber nerves that is the same nerves that innervate the overlying muscles and skin.

A

Parietal peritoneum

33
Q

True or false.

  • The diaphragmatic peritoneum is supplied by the lower six thoracic nerves.
  • The parietal peritoneum in the pelvis is mainly supplied by the obdurator nerve a branch of lumbar plexus.
A

True

34
Q

Is sensitive only to stretch and tearing and is not sensitive to touch pressure or temperature

A

Visceral peritoneum

35
Q
  • Is supplied by autonomic afferent nerves that supply the viscera or are traveling in the mesentaries.
  • Overdistension of a viscous leads to the sensation of pain the mass centuries of the small and large intestines are sensitive to mechanical stretching
A

Visceral peritoneum

36
Q

Which is pale yellow and somewhat viscid, contains leukocytes. It is secreted by the peritoneum and ensures that the mobile visera glide easily on one another.

A

Peritoneal fluid

37
Q

As a result of the movements of the diaphragm and the abdominal muscles, together with the peristaltic movements of intestinal tract, the peritoneal fluid is?

A

Not static

38
Q

True or false.

It seems that intraperitoneal movement of fluid toward the diaphragm is continuous and there it is quickly absorbed into the subperitoneal lymphatic capillaries.

A

True

39
Q

True or false.

The peritoneal coverings of the intestine tend to stick together in the presence of infection.

The greater omentum which is kept constantly on the move by peristalsis of the neighboring track may adhere to the other peritoneal surfaces around a focus of infection in this manner many of the entrepreneur infections are sealed off and remained localized

A

True

40
Q

Plays an important part in suspending the various organs with the peritoneal cavity and serve as a means of conveying the blood vessels lymphatics and nerves to these organs?

A

Peritoneal folds

41
Q

True or false.

Large amount of fat are stored in the peritoneal ligaments and mesentaries and especially large amounts can be found in the greater omentum.

A

True
