Flashcards in Peritoneum, Omentum, Epiploic Spaces, Ligaments, Abnormal Viscera, and Esophagus Deck (48):
1

the parietal peritoneum is derived from

mesoderm

2

what happens after the rotation and development of the greater curvature of the stomach during development

the peritoneal cavity is divided into the greater and lesser peritoneal scas

3

what sac is the main and large part of the peritoneal cavity

the greater sac

4

if i make an incision through the anteriolateral abdomen what sac do i puncture

the greater sac

5

the omental bursa or lesser sac lies where

posterior to the stomach and lesser omentum

6

transverse mesocolon divides the abdominal cavity into what

supracolic compartment
infracolic compartment

7

supracolic compartment contains what

stomach liver and spleen

8

infracolic compartment contains what

small intestine, ascending and descending colon

9

mesentery divides infracolic compartment that is located behind the greater omentum into what two parts

right and left infracolic spaces

10

communication between the supracolic and infracolic compartment hows

through the paracolic gutters
(located on the lateral sides of the ascending and descending colons)

11

what is the sac like cavity that is under the stomach and lesser omentum

the omental bursa

12

the two recess of the omental bursa are

superior and inferior recess

13

which omental recess is limited by the diaphragm superiorly and the posterior ayers of coronary ligament of the liver

superior recess

14

where is the inferior recess of the omental bursa located

between the superior parts of the greater omentum

15

what can be located by running a finger along the gallbladder to the free edge of the lesser omentum

the omentum foramen

16

how many fingers does the omentum foramen permit

2

17

what results in the passage of fluid into omental bursa

preforation of the posterior wall of the stomach

18

an inflammed or injured pancreas can result in what

passage of pancreatic fluid in bursa

(pancreatic pseudo-cyst)

19

what can sometimes happen in regards to objects passing through the omentuem foramen

loop of small intestines and they can be strangled by the edges of the omentum foramen

20

if a loop of small intestine slips through the omental foramen the boundaries cannot be incised why

because they contain blood vessels

21

what must happen to the cystic artery during a cholecystectomy

it must be ligated or clamped and severed during this procedure in order to remove the gall bladder

22

principle viscera of the abdomen are

- terminal part of esophagus
-stomach
-spleen
-intestines
-liver
-bladder
-kidneys
-adrenal glands

23

what divides the liver into right and left lobes

falciform ligament

24

where does digestion mostly occur

in the stomach and duodenum

25

absorption for chemical compunds occurs where

the small intestine

26

most reabsorption of water occurs where

ascending colon

27

atrial supply to the alimentary tract is from?

the abdominal aorta

28

what are the three major branches of the aorta that supply the gut?

celiac trunk
superior mesenteric artery
inferior mesenteric artery

29

what is the main channel of the portal venous system which collects blood from the abdominal part of the alimentary tract

portal vein

30

what is the muscular tube that s 2cm and conveys food from the pharynx to the stomach

esophagus

31

what are the three esophageal constrictions

1. cervical constriction
2. thoracic constriction
3. diaphragmatic constriction

32

what constriction is at the beginning of the pharyngeoesophageal junction

cervical contricion

33

what a compound constriction that is crossed by the arch of the aorta and also by the main brnochus

thoracic constriction

34

what constriction happens at the esophageal hiatus of the diaphragm

diaphragmatic constriction

35

inferior third of esophagus is made up of what muscle? the middle third, superior?

- smooth muscle
-smooth and striated
- striated

36

at what level of vertebra does the esophagus pass through the esophageal hiatus

T10

37

what attahces the esophagus to the margins of the esophageal iatus

phrenicoesophageal ligament

38

where does abdominal esophagus pass after going through the esophageal hiatus

the cardial orifice of the stomach

39

what is the posterior surface of the esophagus covered with

the peritoneum of the omental bursa

40

the right border of the esophagus is continuous with the lesser curvature and the left border is what

separated by the fundus of the stomach by the cardial notch

41

what is the lumen of the esophagus like when one is not eating

it is collapsed, so that food and gastric juices do not go into the esophagus

42

arterial supply for the abdominal esphagus

the left gastric artery and the left inferior phrenic artery

43

lymphatic drainage of the abdominal esophagus is to where

left gastric lymph nodes

44

what is the esophagus innervated by

esophageal plexus

45

when large volumes of blood cause the submucosal vein to englarge it is called

esophageal varices

46

esophageal varcies usually form in who

alcoholics

47

what is the most common form of esophageal discomfort

pyrosis (heartburn)

48

pyrosis can be associated with

hiatal hernia
