Q

What are the four parts of the stomach?

A

Fundus, body, pyloric part, greater and lesser curvatures

2
Q

What is the incisura?

A

The notch at the distal end of the incisura. This occurs proximal to the pylorus

3
Q

The stomach is the most …….. part of the GI tract, is relatively ……. at both ends, but…. in the middle

A

Dilated, fixed, mobile

4
Q

What are the boundaries of the body of the stomach?

A

The body extends from the fundus to the angular notch

5
Q

What are the boundaries of the pyloric part?

A

The pyloric part extends from the angular notch to the gastroduodenal junction (right of the midline around L1??)

6
Q

What six anatomical features make up the bed of the stomach?

A

Left crus, diaphragmatic dome, upper part of the left kidney, and the triangle of the pancreas transversely, spleen upper laterally, and suprarenal upper medially

7
Q

What arteries supply the stomach?

A

Left and right gastric, short gastric, left and right gastroepiploic,

8
Q

What is the blood supply to the lesser curvature?

A

The left and right gastric which anastomose and may be double

9
Q

What is the blood supply to the fundus?

A

The short gastric a. from the splenic

10
Q

What is the blood supply to the greater curvature?

A

The left and right gastroepiploic - which also supply the omentum. Gastric branches come off at right angles (c.f. nerves)

11
Q

Describe the venous drainage of the stomach

A

Identical to the arterial supply however there is no gastroduodenal vein.

12
Q

Where does lymph drain to?

A

Lymph drains to the coeliac nodes. A watershed exists between the lesser and greater curves and LUQ

13
Q

What is the nerve supply to the stomach?

A

Sympathetic fibres for vasomotor and parasympathetic (vagal) which controls motility and secretion

14
Q

What is the course of the nerve supply to the stomach?

A

Anterior to the lesser omentum and a hepatic branch which gives off a pyloric antrum branch, and posterior giving off a large branch to the coeliac ganglion

15
Q

Describe the structure of the stomach wall

A

Outer longitudinal, inner circular layers, reinforced by innermost oblique muscle layer

16
Q

What are the cell types of the body and their function?

A

Parietal cells (acid secreting), which give way to pyloric type G cells (gastrin secreting)
