Flashcards in GI 5 - Hernias + Stomach Deck (30):
1

How does an direct inguinal hernia enter the inguinal canal?

Via Hesselbach's triangle (weakened conjoint tendon)

2

How does an indirect inguinal hernia enter the inguinal canal?

Via Deep inguinal ring

3

What is the most common abdominal hernia?

Indirect inguinal hernia

4

Is a male or female more likely to develop an indirect inguinal hernia?

Male 7:1

5

Why are women more likely to develop a femoral hernia?

Wider hips

6

Name the 2 types of hiatal hernia's:

1) Sliding
2) Rolling

7

What is an incarcerated hernia?

Irreducible hernia, may lead to inflammation and strangulation

8

What is a strangulated hernia?

Blood supply to herniated organ is disrupted = leads to tissue necrosis

9

Which is more likely to become incarcerated: Inguinal or femoral hernia? Why?

Femoral hernia
- Femoral canal is a tighter entrance

10

Name the borders of Hesselbach's triangle:

Lateral: Inferior epigastric vessels
Medial: Lateral border of rectus sheath
Base: Inguinal ligament

11

Name the branch of the aorta which supplies the stomach:

Coeliac trunk

12

Name the 3 branches of the Coeliac trunk:

- Splenic artery
- Left gastric artery
- Common Hepatic artery

13

At which vertebral level does the Coeliac trunk branch from the aorta?

T12

14

Name the arteries which supply the lesser curve of the stomach:

- Left and Right Gastric arteries

15

Name the arteries which supply the greater curve of the stomach:

- Left and Right Gastroepiploic arteries

16

Name the arteries which supply the duodenum:

- Gastroduodenal artery
- Pancreaticoduodenal arteries

17

Which branch of the coeliac trunk passes posterior to the stomach?

Splenic artery

18

What are the main 4 functions of the stomach?

1) Food storage
2) Digestion
3) Defence
4) Motility

19

What is 'receptive relaxation'?

Relaxation of orad stomach due to stimulation of vagus nerve
- Allows food to enter without increasing intra-gastric pressure to avoid reflux = allows food storage

20

What is the pH of the stomach?

pH = 1.5-2

21

NAme some cells lining a gastric gland:

- Stem cells
- Parietal cells
- G cells
- D cells
- Entero-chromaffin-like cells
- Mucous neck cells
- Chief cells

22

What is the role of chief cells in the stomach? Where are they found primarily?

Secrete pepsinogen

Fundus + Body

23

In which part of the stomach are endocrine cells primarily found?

Pylorus

24

What is the role of superficial epithelial cells?

Secrete HCO3-

25

What is the role of Parietal cells?

Secrete:
- HCl acid
- Intrinsic factor

26

Which gastric cells secrete pepsinogen?

Chief cells

27

Which gastric cells secrete HCl acid?

Parietal cells

28

Which gastric cells secrete intrinsic factor?

Parietal cells

29

Which gastric cells secrete Gastrin?

G cells

30
