Q

Left lobe is divided into the lateral segment and medial segment T | F

A

True

29
Q

Right lobe is divided into anterior and posterior segments T | F

A

True

30
Q

Caudate lobe is located where? (caudate is the square shaped small area on liver)

A

Sits between the IVC and fissure for ligamentum venosum.

31
Q

Quadrate lobe

A

It is the more rectangular area it is the more anterior portion of the liver. Sits between GB and fissure of ligamentum venosum (?)(anterior has the same amount of letters as quadrate)

32
Q

Right lobe is divided into _______ and ________ portions.

A

Anterior and posterior

33
Q

Left lobe is divided into _______ and ________ portions.

A

Medial and lateral

34
Q

Which lobe of the liver is the smallest?

A

Caudate lobe

35
Q

Ligamentum teres is also the:

A

Round ligament–connects to umbilicus

36
Q

Caudate lobe is retroperitoneal T | F

A

False (even though IVC is retropertioneal)

37
Q

What marks the surgical/functional division between the right and left lobes of the liver on the anterior surface?

A

Cantlie’s line

38
Q

Anatomical divison?

A

Falciform ligament

39
Q

On the visceral surface of the liver, what separates the posterior caudate lobe from the more anterior quadrate lobe?

A

Porta hepatis

40
Q

What structures make up the “cross bar of the H”?

A

Porta hepatis

41
Q

Which liver lobe is more anterior?

A

Quadrate lobe

42
Q

Gallbladder is:

A

A little resovoir that holds bile. Only attached to the liver by the neck of the GB, everything else is free moving.

43
Q

Gallbladder is divided into:

A

Neck (connected to cystic duct)
Body
Fundus

44
Q

When you eat a fatty meal, the hormonal feedback system controls the flow of bile from the GB into the duodenum. T | F

A

True

45
Q

Describe the fundus:

A

Most inferior and anterior portion, usually the bile will be stored here (because of gravity).

46
Q

What is the fundus in contact with?

A

Duodenum, transverse colon and anterior abdominal wall.

47
Q

Describe the body:

A

Extends upwards from fundus and is in direct contact (but not attached to) the visceral part of the liver. Largerst part.

48
Q

Hartmann’s Pouch (the infindibulum):

A

Common for gallstones to be lodged. Weaker area of the wall, a mucousal fold or slight ***

49
Q

What surface of the liver is the GB located on?

A

Anterior visceral

50
Q

What liver landmark is it located within?

A

Cantlie’s line (within the main lobar fissure)

51
Q

Where is Hartmann’s pouch located?

A

Neck of GB

52
Q

What structure does bile flow through within the parenchyma?

A

Hepatic ducts

53
Q

What part of the GB protrudes from the inferior aspect of the liver?

A

Fundus

54
Q

What portion of the gallbladder is attached to the liver?

A

Neck

55
Q

How many segments of the liver are there?

A

8–because each segment of the liver has its own blood supply.

56
Q

What 2 veins divide the liver?

A

Portal and hepatic

57
Q

In the ceterne of each segment there is a branch of:

A

Portal triad–hepatic artery, portal vein, and bile duct.

58
Q

In the center of each segment, there is a branch of:

A

Portal triad–hepatic artery, portal vein, and bile duct.

59
Q

In the otuer portion of the segment is the

A

Portal vein

60
Q

What are the segments? (Start at back of liver and go clockwise)

A 
Seg1-caudate lobe
Seg2/3-lateral left lobe
Seg4-medial left lobe divided into 4a(sup) and 4b(inf)
Seg5/8-anterior right lobe
Seg6/7-posterior right lobe
61
Q

Left portal vein is more _______: (sup or inf)

A

Superior

62
Q

You are very superior/inferior when you see the IVC:

A

Superior

63
Q

You are very superior/inferior when you see the IVC:

A

Superior

64
Q

What divides the liver into superior and inferior portions?

A

Portal Veins

65
Q

If the portal vein is viewed on a (transverse) scan, you are not sure what segment you are on because you are on the division. T | F

A

True
