Q

Where are the different lobes found?

A

On the anterior surface, the falciform ligament separates the right and left lobe. On the visceral surface, the right lobe is split with the quadrate lobe found anteriorly and inferiorly and the caudate lobe is found posteriorly and superiorly.

Q

Describe four characteristics of the gall bladder

A

– Is made up of three parts – fundus, body and neck– The fundus is surrounded completely by peritoneum, binding is body and neck to the liver– It is attached to the liver via connective tissue of the fibrous capsule of the liver. – The neck of the gall bladder joins the cystic duct

Q

What is the biliary tree made up of?

A

Right and left hepatic ductsCommon hepatic ductCystic duct The common hepatic and the cystic duct join together to form the bile duct. The pancreatic duct joins onto the bile duct just before the ampulla of vater. This then secretes the bile into the duodenum via the ampulla of vater.

Q

What can gall stones cause in each of the four places?

A

Gall Bladder - AsymptomatcCystic Duct – Acute CholecystitisCommon Bile Duct – Biliary ObstructionTerminal Duct – Pancreatitis

19
Q

What artery supplies the gall bladder?

A

Cystic artery

20
Q

Where does the cystic artery arise?

A

In the triangle between the common hepatic duct, the cystic duct and the visceral surface of the liver.– the cystohepatic triangle

21
Q

What arteries branch to give the cystic artery?

A

Coeliac trunkCommon hepaticRight hepaticCystic

22
Q

What are the difference in venous drainage in the differing parts of the gall bladder?

A

Head and fundus – drain into hepatic sinusoids. Neck – flows via the cystic veins either into the liver or though the hepatic portal vein.

23
Q

Where do you find the pancreas?

A

Lying retroperitoneally, overlying L1 and L2 on the posterior abdominal wall. Found posterior to the stomach and in between the duodenum on the right and the spleen on the left. The transverse colon is found attached to its anterior margin. – Is found in the curve of the duodenum.

24
Q

What are the parts that the pancreas is split up into?

A

HeadNeckBodyTail

25
Q

Describe the characteristics of the head of the pancreas

A

Lies in C-curved shape of duodenumSuperior mesenteric vessels are to the left Is just inferior to the transpyloric plane

26
Q

Describe the characteristics of the neck of the pancreas

A

Overlies superior mesenteric vessels (has a groove on its posterior surface for these)Anterior surface is adjacent to the pylorusThe hepatic portal vein is found posterior to the neck.

27
Q

Describe the characteristics of the body of the pancreas

A

Lies to left of superior mesenteric vessels, passing over the aorta and L2 vertebraAnt. surface is covered with peritoneum and is part of the stomach bud

28
Q

What is the posterior surface of the body of the pancreas in contact with?

A

AortaSMALeft suprarenal glandLeft kidney Renal vessels.

29
Q

Where does the tail of the pancreas lie?

A

Anterior to the left kidney

30
Q

Describe teh characteristics of the tail of the pancreas

A

Closely related to the splenic hilum and left colic fixtureTail passes between the layers of the splenorenal ligament with the splenic vessels

31
Q

Where is the main pancreatic duct formed?

A

Begins at the tail of the pancreas running through towards the head. It then turns inferiorly and runs alongside the bile duct until the form the hepatopancretic ampulla of vater

32
Q

What is the ampulla of vater?

A

Close relation of the main pancreatic duct and bile duct which secrete bile acids and digestive enzymes into the descending part of the duodenum.

33
Q

What is the arterial supply to the spleen?

A

Splenic artery (larges branch of coeliac trunk)– branches into five at the splenic hilum to supply the different areas of the spleen

34
Q

What is the course of the splenic artery?

A

Has a tortuous corse posterior to the omental bursa, anterior to the left kidney and along the superior border of the left pancreas.

35
Q

What is the venous drainage to the spleen?

A

Splenic vein, the inferior mesenteric vein and the superior mesenteric vein forming the hepatic portal vein posterior to the neck of the pancreas.

36
Q

What does the ligamentun teres represent?

A

The approximation between the right and left lobes of the liver

37
Q

At what level does the coeliac artery arise?

A

T12Found immediately after the descending thoracic aorta passes through the crura of the diaphragm and its name changes to the abdominal aorta.

38
Q

What are the branches of the coeliac trunk?

A

Left GastricSplenicCommon Hepatic

39
Q

Descreibe the branching from the Common Hepatic Artery

A

Branches into the Proper hepatic artery which supplies the liver and the gastroduodenal artery

40
Q

What is the uncinate process?

A

A projection from the inferior portion of the head of the pancreas.

41
Q

What is the main function of the spleen?

A

Detects, removes and destroys expended blood cells and broken down platelets. It also recycles globin and iron.

42
Q

What arteries supply the stomach?

A

Short gastric = fundusLeft gastric = lesser curvatureRight gastroepiploic = greater curvatureGastroduodenalLeft gastroepiploic = left side of greater curvature

43
Q

Which arteries anastamose around the stomach?

A

Right and left gastric arteriesRight and left epiploic arteries
