The fundus glands (or fundic glands, or gastric glands) are found in the body and fundus of the stomach.

They are simple tubes, two or more of which open into a single duct.

[edit] Pathology

Fundic gland polyposis is a medical syndrome where the fundus of the stomach develops many polyps.

[edit] Types of cells

Location	Name	Description	Secretion	Staining
Isthmus	goblet cells	In gastric pits.	mucus gel layer	Clear
Neck	parietal (oxyntic) cells	Between the chief cells and the basement membrane, larger oval cells, which stain deeply with eosin, are found; these cells are studded throughout the tube at intervals, giving it a beaded or varicose appearance. These are known as the parietal cells or oxyntic cells, and they are connected with the lumen by fine channels which run into their substance.	gastric acid and intrinsic factor	Acidophilic
Base	chief (zymogenic) cells	At the point where they open into the duct, which is termed the neck, the epithelium alters, and consists of short columnar or polyhedral, granular cells, which almost fill the tube, so that the lumen becomes suddenly constricted and is continued down as a very fine channel. They are known as the chief cells or central cells of the glands.	pepsinogen, rennin	Basophilic
Base	enteroendocrine (APUD) cells	G cells are a type of enteroendocrine cell that secrete the hormone gastrin (gastrin promotes the secretion of pepsinogen (by cheif cells) and HCl (by parietal cells) and promotes gastric contractions to mix contents).	hormones	-

Anatomy of torso, digestive system: Gastrointestinal tract

Upper GI

To stomach	Mouth • Pharynx (nasopharynx, oropharynx, hypopharynx) • Esophagus (UES, LES) • Crop

Stomach	rugae – gastric pits – cardia/gland – fundus/gland – pylorus/gland – pyloric antrum – pyloric canal – greater curvature – lesser curvature – angular incisure

Lower GI

Intestine: small	Duodenum (Suspensory muscle, Major duodenal papilla, Minor duodenal papilla) • Duodenojejunal flexure • Jejunum • Ileum • Ileocecal valve continuous (intestinal villus, crypts of Lieberkühn, circular folds)

Intestine: large	Vermiform appendix • Cecum • Colon (ascending colon, hepatic flexure, transverse colon, splenic flexure, descending colon, sigmoid colon) continuous (taenia coli, haustra, epiploic appendix)

Termination	Rectum: Houston valve • rectal ampulla • pectinate line Anal canal: anal valves • anal sinuses • anal columns • Hilton's white line Anus: Sphincter ani internus muscle • Sphincter ani externus muscle

Lymph	GALT: Peyer's patches (M cells)
