1
Q

Describe mucous neck cells. In the stomach.

A

Similar to surface cells, but provides a soluble mucus. Located in the neck of the stomach glands.

2
Q

Describe chief cells.

A

Basophilic protein-secreting cells (have a rough ER in abundance. Found in the base of glands

3
Q

What type of glandular cell secretes pepsinogen in the stomach?

A

Chief cells.

4
Q

How is pepsin (secreted by chief cells) turned into pepsinogen in teh stomach?

A

By HCl present in the stomach

5
Q

Describe parietal cells.

A

Large eosinophilic cells that secrete HCl. FOund in the middle 1/3 of glands

6
Q

Describe s enteroendocrine cells.

A

Small cells resting on the basal lamina, that produce gastrointestinal hormones

7
Q

What type of glandular cells in the stomach are characterized by zymogen granules?

A

chief cells

8
Q

What part of the parietal cell communicates with the apical surface of stomach glands and produces/delivers HCl to the gland?

A

Intracellular canalicular system

9
Q

What do parietal cells create/deliver?

A

HCl and Intrinsic Factor

10
Q

What 3 major receptors control HCl secretion in parietal cells?

A

Gastrin receptors
Histamine (H2)
Ach (M3)

11
Q

Where are enteroendocrine cells found within gastric glands?

A

At everly level of the gland

12
Q

What types of cells are in fundic-type gastric glands/

A

Mucus Neck, Parietal, Chief, Enteroendocrine

13
Q

What types of glands are in pyloric-type gastric glands?

A

Mainly mucous and a few enteroendocrine

no chief, no parietal

14
Q

Describe fundic gastric glands?

A

Simple, branched, tubular

15
Q

Describe Pyloric gastric glands.

A

Coiled branched, tubular

16
Q

Describe cardiac gastric glands.

A

similar to pyloric, but shorter

coild branced tubular

17
Q

Describe what types of cells are in cardiac gastric glands.

A

A lot like pyloric glands so they only have mainly mucous and a few enteroendocrine

no chief, no parietal
