Flashcards in 9 28 Anatomy-Table 1 Deck (66):
1

what is a coelom

a hollow cavity

2

what are the 4 coelum of the body?

2 plural sacs, the paracardial sac, the peritoneium sac in the abdominum

3

what is mesothelium

simple squamus epithelium

4

is the GI tract in the Coelum?

no! because the fist is not in the balloon. or because the mesothelium is surrounding the GI track

5

what is peritoneium

it is mesothelium (describes the type of tissue) or it is the sac or coelom in the abdominal cavity

6

what is parietal

it is a "wall"

7

the pariatal peritonium

the peritoneum around the wall of the abdominal

8

mesentery peritoneum

the two layer region or double membrane that connects the GI tract to the parietal peritoneum of the abdominal wall. formed when the GI tract pushes into the peritoneum.

9

visceral peritoneum

the peritoneium that is right around the GI tube!

10

what are the intraperitoneal organs

an organ that is covered in visceral peritoneal...pretty much the whole gi tract!

11

what organs are not projecting into the celomic cavity?

the duodenum (2-4), cecum, ascending colon, and descending colon.

12

what is a secondary retroparitoneal organ

they pushed into the peritoneal and then bent over and retracted back out of the peritoneal (withdrew out of the balloon and just touching the balloon now.)

13

how do we get blood to the GI tract?

they go inbetween the two layers of the mesentary!

14

what structures course through the Mesentary

arteries viens lymphatics and nerves

15

how do we innervate the parietal peritoneum?

intercostal nerves give somatic innervation

16

what types of pain are the peritoneum most sensitive?

vibration!

17

what provides innervation to the diaphagmatic pariatal paratinium?

the phrenic nerve from C3,C4,C5

18

why could the right shoulder hurt if spleen or galbladder is inflamed?

the diaphragmatic parital peritinium is inervated by C3,C4,C5! this is the one instance of somatic nerve refering to a somatic nerve!

19

what provides innervation to the visceral peritoneum?

visceral afferent neurons from the pre-aortic gangleon!

20

what are the three main components of the GI tract

the stomach; the small intestines and the large intestines.

21

what are the regions of the stomach?

the cardia; fundus; body (lesser and greater curvatures); gastric rugae; pylorus; lesser omentum; greater omentum.

22

what is the cardia

the portion ajacent to where the esophagus enters into the stomach; (it is closest to the heart)

23

what is the fundus?

the domed shaped portion near the top where gas can accumulate

24

the body of hte stomach? what is it?

the main part that has two curvatures and has gastric rugae or ridges that help to expand when we eat

25

what is the pylorus?

it is the ind of the stomach where the pyloric shpinctor is to keep the flow of food one-way

26

what is the lesser omentum

the mesentary that goes from the lesser to the liver: two components: the Hepatoduodenal ligament and the hepatogastric ligament depending on whether it is attached to the duodenal or the stomach.

27

what is behind the lesser omentum?

the epiploic foramen that leads to the lesser sac

28

Greater omentum...what the what?

has lymphnodes, adipose tissue and blood. It will encoumpus infection and provide lymph drainage where needed.

29

where does the greater omentum connect?

it conects to the bottom of the stomach and then loops back up to the transvers colon (apron like four layers)

30

What are the parts of the small intestine?

the duodenum, the jejunum, ilieum

31

What are the 4 parts of the duodenum?

1: superior; 2: descending; 3: transverse; 4: ascending

32

1st part or the superior part fo the duodenum

the end of the stomach, the highest part, also the duodonum bulb or cap in x-ray images. It is smooth walled and inraperitoneial, and the place for duodenual ulcers

33

2nd or descending part of duodenum

the bile duct and the pancreatic duct connects here at the ampulla of vater, and right below this is the division of the forgut and midgut

34

3rd part or transverse duodenum

superior mesonteric artery and superior mesonteric vein that go over the top! vien always right and artery is left

35

4th or Ascending part

Ligament of treitz that goes from the diaphram and attaches to the end of the duodenum and start of the jejunum

36

the jejunum:

Upper left quadrent starts of the ligament of treitz and has numerous plicae circulaire (circular folds).

37

The Illium

Lower right quadrent: fewer circular folds, less absorption: peyer's patches or dense lymphnoid patches to fight infection.

38

Large intestine has the following parts:

Cecum, ascending colon; transveerse colon; descending colon; sigmoid colon; rectum/anus

39

Cecum description

blind ended pouch in the bottom right quadrent where the illium empties.

40

the appendix

the visidual off of the cecum

41

how to find the appendix?

find the ASIS (anterior superior illiac spine) and the Umbilicus, draw a line and about 1/3 the way is the mcburney's point where the junction of the ilium and the the cecum

42

the ascending colon

the part in the right of the abdomen to the hepatic flexure or right colic flexure

43

the transverse colon

from the right colic flexure to the splenic flexure or left colic flexure

44

descending colon

from the left colic flexure to the left lower quadrent

45

Haustra

the small pouches of the colon caused by sacculation

46

the sigmoid

the curved section to the rectum

47

the rectum

the straight shot to the anus

48

the anus

the skeletal muscle that controls the output.

49

What are the accessory digestive glands?

Liver, Biliary tract, pancreaus

50

What are the parts of the liver

falsiform ligament, right lobe, left lobe, quadrate lobe, caudate lobe, porta hepatis

51

Falciform ligament

mesentary that seperates the right and left lobe, right at the bottom is the round ligament that houses the abliterated umbelical vein that brought oxygenated blood to the baby from mummy.

52

Right lobe

the largest

53

left lobe

the one on the other side of hte ligament

54

Quadrate lobe

looks like it has four sides formed form the Gall bladder and the ligament, and the porta hepatis (it is on the bottom of the liver.

55

Caudate lobe?

on the tale or back side of the liver above the porta hepatis

56

what are the three structures of hte porta hepatis on the bottom of the liver?

1. bile ducts, 2. hepatic arteries, 3. Portal veins.

57

Bile ducts?

the biliary structure that takes bile from the liver and gallblader to the duodenum

58

hepatic arteries

bring oxygenated blood to the liver

59

portal vein

deoxygenated but nutient rich blood from the intestines

60

parts of the biliary tract

Hepatic ducts; common hepatic duct; gall bladder; cystic duct; common bile duct.

61

Hepatic ducts

the bile ducts inthe liver itself from the left and right (left and right hepatic ducts) these come together to form the common duct

62

gall bladder and path to the intestines

inferior surface of the liver, store and concentrate bile. When release colesystic kina hormone from the duodenum cause the release of bile to the cystic duct and then to the common bile duct and to the ampular vontar to the duadunum.

63

what are the two funcitons of the pancreus?

endocrine and exocrine

64

what is the endocrine function of the pancreas?

islets of langerhan Alpha and Beta for the Beta cells to secrete insulin

65

what is an Exocrine gland:

gland that secretes to an epithelial lined surface: such as the duodenum!

66

what are the paths of the enzymes out of the pancreus

the main and accessory pancreatic ducts.
