Histology Fact Sheet: Stomach

 

The folds of the empty stomach are called rugae.

The epithelium on the stomach is lined by mucous surface cells which are a simple columnar epithelium.

Chief cells secrete pepsinogen. Pepsinogen is the precursor for pepsin. Parietal cells are also called oxyntic cells. They secrete hydrochloric acid and intrinsic factor. Mucous neck cells contain mucinogen granules.
