1
Q

What is the pancreas?

A

• An elongated, acessory digestive gland that lies retroperitonealy.

2
Q

At what verterbral level can you find the pancreas?

A

• L1 + L2

3
Q

Where does the pancreas lie in relation to other organs?

A
  • Posterior to the stomach
    • Between the duodenum and the spleen

Transverse mesocolon attaches to its anterior margin

4
Q

What are the four parts of the pancreas?

A
  • Head
    • Neck
    • Body
    • Tail
5
Q

Where can the head of the pancreas be found?

A

• In the C-shaped curve of the duodenum

6
Q

What does the neck of the pancreas overly?

A

• Superior mesenteric vessels

7
Q

Where does the main pancreatic duct begin?

A
  • At the tail of the pancreas and runs through the glans to the head
    • Then turns inferiorly and is closely related to the bile duct
8
Q

What do the pancreatic duct and bile duct join together to form?

A

• Hepatopancreatic ampulla of vater which opens into duodenum

9
Q

Where is the arterial supply of the pancreas derived from?

A

• Branches of the splenic artery

10
Q

What two arteries do the pancreatic arteries form arches with?

A
  • Gastroduodenal

* Superior mesenteric arteries

11
Q

Where does the splenic artery come from? List the arteries leading to pancreastic arteries

A

Coeliac trunk -> Splenic artery -> Pancreatic

12
Q

What are the names of the gastroduodenal arterial supply of the pancreas?

A

• Anterior and posterior superior pancreaticoduodenal arteries

Anterior and posterior inferior pancreaticoduodenal arteries

13
Q

What are the names of the superior mesenteric arterial supply to the pancreas?

A

• Pancreaticoduodenal arteries form anteriorly and posteriorly placed arches that supply the head

14
Q

What is the venous drainage of the pancreas?

A
  • Pancreatic veins which correspond to arterial supply
    • Pancreaticoduodenal veins are the main one
    • Empty into splenic vein and superior mesenteric vein
15
Q

Describe the spleen

A
  • An ovoid, purplish pulpy mass about the size and shape of a fist
    • Delicate
16
Q

Where is the spleen located?

A

• Upper left quadrant or hypochondrium of the abdomen, resting on left colic flexture ?

17
Q

What is the spleen covered by, and what is the only exception to this?

A

• Layer of visceral peritoneum, except at the splenic hilum

18
Q

What are the anterior relations of the spleen? What is the attachement?

A
  • The stomach

* Attached by the gastrosplenic ligament

19
Q

What is the posterior relation of the spleen

A

• The left part of the diaphragm, which separates it from the pleura, lung and ribs 9-11

20
Q

What is the inferior relation of the spleen?

A

The left colic flexure

21
Q

What is the medial relation of the spleen? What is the attachment?

A

• The left kidney

Attached by the splenorenal ligament

22
Q

What is the arterial supply of the spleen?

A

• Splenic artery, the largest branch of the coeliac trunk

23
Q

What is the course of the splenic artery?

A

• Travels posterior to the omental bursa, anterior to the left kidney and along the superior border of the pancreas

24
Q

What is the venous drainage of the spleen?

A
  • Splenic vein
    • Drains into Inferior mesenteric vein which runs posterior the body and tail of the pancreas throughout most of its course
25
Q

What does the splenic vein unite with posterior to the neck of the pancreas?

A

• The superior mesenteric vein to form the hepatic portal vein
