Neck Infundibulum:

A

S-shaped spiral mucosal folds (of Heister)

21

peritoneal attachment (mesentery) to liver, which usually contains cystic a
A

22
Q

Neck Infundibulum:

Lies anterior to

A

2nd part of the duodenum

23
Q

Bile produced by ?

Flows through ?

A

Hepatocytye

Bile canaliculi , bile ductules, bile duct

24
Q

Bile canaliculi , bile ductules, bile duct These structures gradually merge, forming a
converging network that ultimately forms

A

The common hepatic duct

25
Q

The common hepatic duct joins the cystic duct from the gallbladder and cont to the duodenum as

A

The common bile duct

26
Q

Left hepatic duct is formed by the union of ————-,

most often behind or to the left of the umbilical portion of the left portal vein

A

segment II and III ducts,

27
Q

Biliary drainage of segment IV is more variable but is usually by a single
duct into the

A

left hepatic duct.

28
Q

Right hepatic duct is formed by the union of——— wich drains segment ———- and ——— which ddrains segments sectoral
ducts.

A

right anterior (medial) , V and VIII

posterior (lateral) VI and VII

29
Q

Right posterior (lateral) sectoral duct usually curves around the—————- before fusing with its medial aspect

A

duct or may drain into both hepatic ducts

32
Q

Right hepatic duct and its branches are ——————— than the left ductal system

A

more often subject to variation

33
Q

Luschka’s duct

A

A small bile duct from segment V of the liver may
traverse gallbladder fossa and join right hepatic
duct or its anterior sectoral branch or the common
hepatic duct.

34
Q

Luschka’s duct

its importance lies

A

in the fact that it may be injured

during cholecystectomy, causing a postoperative bile leak.

35
Q

An oblique groove on the inferior surface of the liver
posterior to gallbladder bed is present in 70–80% of
livers. • It is variably known as the

A

fissure of Gans, Rouviere’s

sulcus or the incisura hepatis dextra

36
Q

It overlies the division of the right posterior (lateral)
portal pedicle, where it gives off the inferior segment
VI branch. • It has been increasingly recognized as a useful
anatomical landmark during hepatic resection and in
laparoscopic cholecystectomy
• (since cystic duct and artery lie anterosuperior to
the sulcus while CBD lies posteroinferior)

37
Q

Sectoral ducts secrete bile via

A

Right and left hepatic ducts

38
Q

Right and left hepatic ducts fuse into ————— in the ———

A

Common hepatic duct

Lateral part of the oorta hepatis

39
Q

Neck of gallbladder funnels off into short

A

Cystic duct

40
Q

Cystic duct combines with common helatic duct to form

A

Commin buke duct ( CBD )

41
Q

Common bile duct united with pancreatic duct to form

A

Ampulla of vater

hepatopancreatic ampulla

42
Q

Ampulla of vater

(hepatopancreatic ampulla) opens into

A

duodenum on the major duodenal

papilla.

43
Q

The flow of bile and pancretic juice is controlled by

A

Sphincter of Oddi

44
Q

Right and left hepatic ducts to emerge
from liver and unite near ———— to form the common
hepatic duct.

A

right end of

porta hepatis

45
Q

Extrahepatic right + left duct

A

Right ; is short and nearly vertical

Left ; longer, more horizontal

46
Q

Extrahepatic left duct lies along

A

Inf border of segment 4

47
Q

Accessibility of extrahepatic segment of
left hepatic duct is exploited when
performing a

A

surgical biliary bypass in
patients with benign hilar bile duct
strictures.
