1

What is the appendix?

A narrow tube containing lymphoid nodules at the base of the caecum where the 3 tenia coli meet

2

What is the position of the tip of the appendix?

Variable - most commonly retrocaecal

3

What are the four parts of the colon?

Ascending colon, transverse colon, descending colon, sigmoid colon

4

What is the junction between the ascending colon and transverse colon?

Hepatic flexure

5

What is the junction between the transverse colon and descending colon?

Splenic flexure

6

What is the muscle of the rectum?

Redevelops one continuous longitudinal muscle coat - no tenia coli

7

In which quadrant is the liver?

RUQ

8

What are the 2 surfaces of the liver?

diaphragmatic surface and visceral surface

9

What demarcates the two surfaces?

The inferior margin of the liver

10

What divides the diaphragmatic surface into 2 lobes?

The falciform ligament

11

What is the falciform ligament?

A double fold of peritoneum from the anterior abdominal wall

12

What runs in the free inferior edge of the falciform ligament?

The ligamentum teres (the obliterated umbilical vein)

13

What divides the visceral surface of the liver into 4 lobes?

a H shape

14

What is the cross piece of the H?

The hilum of the liver

15

What are the four lobes of the visceral surface of the liver?

The left lobe, the right lobe, the quadrate lobe and caudate lobe

16

What is between the right lobe and the quadrate lobe?

The gall bladder

17

What is between the left lobe and the quadrate lobe?

The ligamentum teres

18

What is the between the right lobe and the caudate lobe?

The IVC

19

What is between the left lobe and the caudate lobe?

The ligamentum venosum

20

What structures enter at the hilum of the liver from anterior to posterior?

hepatic duct, hepatic artery, portal vein

21

Where are the portal triad transmitted through?

The free edge of the lesser omentum

22

What is the venous drainage of the liver?

The hepatic vein - comes straight out of liver into the IVC - doesn’t go through hilum

23

What is the cystic duct?

The duct from the gall bladder containing bile

24

What is the common hepatic duct?

The duct from the liver - combination of the left and right hepatic duct

25

What is the common bile duct?

The cystic duct and the common hepatic duct

26

What is the path of the common bile duct?

Descends in the free edge of the lesser omentum,slips behind the first part of the duodenum and then behind the head of the pancreas and then empties in the major duodenal papilla

27

What is the sphincter of odi?

The sphincter around the pancreatic duct and the common bile duct at the major duodenal papilla - allows bile to back up into the gall bladder

28

What are the features of the gall bladder?

A fundus, body and neck

29

What are the features of the pancreas?

Head, neck, body and tail

30

What is the uncinate process?

A wedge shaped projection of the head of the pancreas

31

Where is the neck of the pancreas?

Deep to the pylorus, over the vertebral column, IVC and aorta

32

Where is the body of the pancreas?

Above the DJ flexure, over the vertebral column, IVC and aorta

33

Where is the tail of the pancreas?

At the hilum of the spleen

34

Where does the principle pancreatic duct drain from and into?

From the tail into the major duodenal pailla

35

Where does the accessory pancreatic duct drain from and into?

From the lower part of the head and uncinate process into the minor duodenal papilla

36

In what quadrant is the spleen?

LUQ

37

What are the two surfaces of the spleen?

Diaphragmatic surface and visceral surface

38

What demarcates the two surfaces?

A notched line

39

What structures enter at the hilum of the spleen?

Splenic artery and splenic vein

40

Which ribs is the spleen associated with?

Ribs 9, 10, 11
