Where is the gall bladder?

Peritoneal
Right hypochondriac region
Between right and quadrate lobes of the liver on inferior aspect

1

What three parts can the gallbladder be divided into?

Fundus
Body
Neck

2

Where in the gallbladder neck is a common location for gallstones to get stuck?

Hartmann's pouch - a mucosal fold

3

What is the ampulla of vater?

Where the common bile duct joins the pancreatic duct

4

What is the major duodenal papilla?

Where the pancreatic duct opens into the duodenum

5

What regulates the opening of the major duodenal papilla?

Sphincter of Oddi

6

Arterial supply of the gall bladder?

Coeliac trunk - hepatic artery proper - cystic artery

7

Venous drainage of the gall bladder?

Cystic vein into the portal vein

8

Innervation of the gall bladder?

Sympathetic and sensory - celiac plexus
Parasympathetic - vagus nerve

9

Which branch of the autonomic nervous system causes the gall bladder to contract?

Parasympathetic

10

Is the pancreas peritoneal or retroperitoneal?

Retroperitoneal except for the tail

11

Where is the pancreas located?

In the epigastrium and left hypochondrium regions

12

What are the sections of the pancreas called?

Head - fits in curve of duodenum
Uncinate process - projection arising from lower part of the head
Neck - over lies superior mesenteric vessels
Body - crosses midline of human body, behind the stomach
Tail - near hilum of spleen

13

What is the tail of the pancreas contained in?

The splenorenal ligament along with splenic vessels

14

Structure of the exocrine pancreas?

Exocrine compartment is a serous gland
Made up of berry-like cells - acini
Connected by intercalated ducts
These drain into interlobular ducts
Into the pancreatic duct which runs the length of the pancreas

15

Arterial supply of pancreas?

Pancreatic branches of splenic artery

Head supplied by:
- gastroduodenal - superior pancreatic duodenal artery
- SMA - inferior pancreatic duodenal artery

16

Venous drainage of the pancreas?

Body and neck drain into the splenic vein
Head drains into superior mesenteric vein and portal vein

17

Where is the spleen located?

Upper left quadrant
Left hypochondrium
Rests on left colic flexure

18

What is the spleen covered in?

Visceral peritoneum
Except for at the splenic hilum

19

What enters and leaves the spleen at the splenic hilum?

Splenic branches of splenic artery and vein

20

What is anterior, posterior and medial to the spleen

Anterior - stomach and gastrosplenic ligament
Posterior - left part of diaphragm
Medial - left kidney and splenorenal ligament

21

Arterial supply of the spleen?

Splenic artery

22

Describe the route of the splenic artery

Tortuous route
Posterior to omental bursa, anteriorly to left kidney, along superior border of pancreas
Between layers of splenorenal ligament, divides into 5 or more branches which enter the hilum, supplying different vascular segments

23

Venous drainage of the spleen?

Splenic vein

24

Describe journey of the splenic vein

Formed by several tributaries that emerge from the hilum
Joined by inferior mesenteric vein
Runs posteriorly to body and rail of pancreas through most of its course
Unites with SMV posterior to the neck of the pancreas to form the hepatic portal vein
