Flashcards in Session 6 - Anatomy of the liver, gall bladder, pancreas and spleen Deck (56):
1

What is the largest gland in the body?

The liver

2

How are nutrients conveyed to the liver?

• Via the portal venous system

3

Where can the liver be found?

• Right upper quadrant of the abdomen • Deep to ribs 7-11 on the right side

4

What is the hypochondrium?

• The part of the abdomen immediately deep to the ribs

5

What is A?

• Left lobe

6

What is B?

Falciform ligament

7

What is C?

• Round ligament of liver

8

What is D?

Inferior border of liver

9

What is E?

• Gall bladder

10

What is F?

• Right lobe

11

What is G?

• Coronary ligament

12

What is H?

• Left triangular ligament

13

What is A?

Cystic area

14

What is B?

• Hepatic duct

15

What is C?

• Portal vein

16

What is D?

• Inferior vena cava

17

What is F?

• Porta hepatis

18

What is G?

• Quadrate lobe

19

What is H?

• Falciform ligament

20

What is I?

• Round ligament

21

What are the two surfaces of the liver?

• Convex diaphramatic surface ○ Anterior, superior and some posterior • Visceral surface ○ Posteroinferior

22

What are the two surfaces of the liver separated by?

• Sharp inferior border the follows the right costal margin inferior to the diaphragm

23

What exists between the diaphragm and the liver?

• The subphrenic recess

24

What are the right and left subphrenic recesses divided by?

• The falciform ligament, which extends between the liver and the anterior abdominal wall

25

What is the space immediately below the liver called?

• The subhepatic space

26

What is the falciform ligament a derivative of?

The ventral mesentery

27

What does the falciform ligament contain?

• The ligamentum teres, an embryological remnant of the umbilical vein

28

What is the bare area of the liver?

An area not convered by visceral peritoneum, but lies in direct contact with the diaphragm

29

What is the deep groove in the bare area of the liver used for?

IVC runs through it

30

What is the coronary ligament?

• Peritoneal reflections that hold the liver to the surface of the diaphragm Borders demarcate boundaries

31

Give three ligaments of the liver and their attachments

• Coronary ligament - attaches to diaphrag, • Right triangular ligament - passes to diaphragm • Left triangular ligament - passes to diaphragm • Falciform ligament - Attaches liver to anterior body wall

32

What is the porta hepatis?

• Ä transverse fissues where vessels (hepatic portal vein, hepatic artery and lymphatics) drain

33

What is the liver split into?

• Two anatomical and two accessory lobes

34

What divides the right and left lobe?

• The falciform ligament divides the right lobe from the left

35

What are the four lobes of the liver?

• The quadrate lobes • The caudate lobe • Right and left lobes

36

What divides the quadrate lobe from the caudate lobe?

• The porta hepatis • The right and left sagittal fissures

37

Which is at the front of the liver, the quadrate or caudate lobes?

• Quadrate

38

Where does the gall bladder lie?

• In the fossa for the gall bladder of the visceral surface of he liver

39

How much bile can the gall bladder hold?

50ml

40

How is the gall bladder bound to the liver?

• Periotneum surrounding its fundus and body • Connective tissue of fibrous capsule of liver

41

What are the three parts of the liver

• Fundus • Body • Neck

42

What does the neck of the gall bladder join onto?

Cystic duct

43

What are the billiary ducts?

• Convey bile from the liver to the duodenum

44

Outline passage of bile to the cystic duct from hepatocytes

• Hepatocytes -> Interlobular billary ducts -> Collecting bile ducts -> Right and left hepatic ducts -> common hepatic duct

45

Outline the passage of bile after it's left the common hepatic duct

• Joins the cystic duct -> Bile duct -> Ampulla of vater (mixed with enzymes from pancreas

46

What do gall stones in gall bladder cause?

• Asymtpomatic

47

What do gall stones in cystic duct do?

• Acute cholecystitis

48

What do gall stones in common bile duct do?

• Biliary obstruction

49

What do gall stones in terminal duct/ampulla of vater do?

Acute pancreatitis

50

What are the main tributaries of the hepatic portal vein?

• Superior mesenteric and splenic veins Gastric and cystic veins

51

Whatis the arterial supply of the gall bladder and cystic duct?

• Cystic artery

52

Where can the cystic artery be found?

• Triangle between the common hepatic duct, cystic duct and visceral surface of liver • Called cystohepatic triangle

53

Give the derivation of the cystic artery

• Coeliac trunk -> Common hepatic -> Right hepatic -> Cystic

54

What is the venous drainage of the neck of gall bladder and cystic duct?

• Cystic veins

55

What happens to the cystic veins which drain from the neck?

• Enter the liver directly or drain through the hepatic protal vein

56

What happens to the venous drainage from fundus and body of the gall bladder?

• Passes directly into the visceral surface of the liver and drains into the hepatic sinusoids
