A

IVC
Right renal artery and vein
Left renal vein

23
Q

What might form a groove in the posterior/superior aspect of the head of the pancreas? (or maybe even within the substance of the pancreas)

A

The bile duct

24
Q

What is the bile duct?

A

A muscular duct through which bile passes from the liver and gall bladder to the duodenum

25
Q

What is the purpose of bile?

A

To help break down fat in the duodenum

26
Q

What is anterior to the pancreas?

A

The transverse colon and mesocolon and jejunum

27
Q

What is in the lower part of the head of the pancreas?

A

The uncinate process

28
Q

What does uncinate mean?

A

“Having hooks or barbs”

29
Q

What is the uncinate process crossed by anteriorly?

A

Superior mesenteric vessels

30
Q

How long is the pancreas?

A

15cm long

31
Q

How long is the neck of the pancreas?

A

1.5-2cm long

32
Q

What passes anteriorly and posteriorly along the border of the head and neck of the pancreas?

A

Anteriorly: Groove for gastroduodenal artery
Posteriorly: Posterior union between the superior mesenteric vein and the splenic vein forming the Portal vein

33
Q

What does the superior mesenteric vein join to form the portal vein?

A

The splenic vein

34
Q

What surface of the pancreas is covered by peritoneum?

A

The anterior surface

35
Q

What is anterior to the whole neck of the pancreas?

A

The pylorus of the stomach

36
Q

What does the body of the pancreas cross over?

A

The aorta and L2

37
Q

Where does the pancreas lie in relation to the lesser peritoneal sac?

A

Posteriorly

38
Q

What is posterior to the body of the pancreas?

A

The aorta, superior mesentric artery, left supra renal gland, left kidney and vessels, left crus of the diaphragm and the splenic vein

39
Q

What is anterior to the body of the pancreas?

A

Covered with peritoneum, lies in the floor of the mental bursa

40
Q

What is posterior to the tail of the pancreas?

A

The left kidney

41
Q

Between the layers of what ligament does the tail of the pancreas pass?

A

The splenorenal ligament

42
Q

Where is the main pancreatic duct found and where does it run?

A

From the tail through to the head, in the posterior aspect of the pancreas

43
Q

What does the main pancreatic duct do when it reaches the neck of the pancreas?

A

It turns down, backward and to the right towards the bile duct

44
Q

What does the joining of the main pancreatic duct and the bile duct create?

A

The hepatopancreatic ampulla

45
Q

Where does the hepatopancreatic ampulla open into?

A

The descending part of the duodenum at the site go the major duodenal papilla

46
Q

Where is the Sphincter of the pancreatic duct found?

A

Around the terminal part of the pancreatic duct

47
Q

Where is the Sphincter of the bile duct found?

A

Around terminal part of the bile duct

48
Q

Where is the Hepatopancreatic sphincter (sphincter of Oddi) found?

A

Around the hepatopancreatic ampulla

49
Q

What are the sphincters around the ducts made of and what do they do?

A

Made of smooth muscle, they control the flow of bile and pancreatic juice

50
Q

What does the accessory pancreatic duct do and where is it found? What % of these ducts drain into the main pancreatic duct?

A

It drains the inferior part of the head of the pancreas and opens into the duodenum (minor duodenal papilla). In 60% of cases it can drain into the main pancreatic duct

51
Q

What is the arterial supply of the pancreas?

A

Mainly from branches of the splenic artery (up to 10 branches)

Branches from the gastroduodenal - anterior and posterior superior pancreaticoduodenal arteries

Branches from the SMA - anterior and posterior inferior pancreaticoduodenal arteries

52
Q
