Title: Parietal cell in the fundus of the stomach (human)
Description: (A) Scheme and (B) electron micrograph of a parietal cell.
The gastric glands contain parietal cells or oxyntic cells. These cells are rich in large mitochondria (3) with many cristae. They export their products (HCl and intrinsic factor)) via secretion canaliculi (2) that are stuffed with microvilli (see inset in (A).
The canaliculi are in close contact with the small tubules (4) and transport vesicles (tubulo-vesicle system).
Intrinsic factor is coupled to vitamin B12, facilitating their resorption in the small intestine.
The chief cell (5) contains proteolytic enzymes packed in electron gray granules.
Entero-endocrine cells are also found in that area, having small electron dense granules (6), with products such as serotonin, histamine and gastrin.
