1

Anatomical regions of the stomach

G-E Junction
Cardia
Fundus
Body
Antrum
Pylorus
Duodenum

2

Cardia

Adjacent to the esophagus

3

Fundus

Above G-E junction

4

Body

Most of the stomach

5

Antrum

Beginning of the outflow tract

6

Pylorus

Outflow tract

7

Epithelium - Antrum & Pylorus

Mostly mucous glands
Also G-Cells

8

Epithelium - Body

Parietal Cells - IF and Protons
Chief Cells - Pepsinogen

9

Ruggal Folds

In Stomach!
Increase surface areaf

10

Layers of the gastric wall

Mucosa
Submucosa
Muscularis propria
Serosa

11

3 Layers of the mucosa

Lamina propria

Bidirectional
Provides propulsion

13

Esophagus - Serosa?

Has no serosa. Only has adventitia!

That means no mesothelial lining. Only loose connective tissue!

14

Body - Oxyntic Glands

Parietal Cells
Chief Cells

15

Parietal Cells - On Histo

Fried Egg

16

Chief Cells - On Histo

Bluer

17

Normal gastric antral mucosa - On Histo

G-Cells

18

G-Cells

Secrete gastrin in response to high pH
Gastrin stimulates parietal cells to increase acid production!

19

Gastritis - Causis

H. Pylori Infection
NSAID/other "chemical gastritis-Reactive gastropathy
Autoimmunity
