Palatal rugae or transverse palatine folds are asymmetrical and irregular elevations of the mucosa located in the anterior third of the palate and are permanent, prominent and unique for individuals and thus can be used as identification for forensic purposes widely in edentulous patients wherein no teeth are present …
What is palate rugae?
Rugae are the anatomical folds that are located on the anterior third of palate behind the incisive papillae. They are also known as “Plica palatine,” and the study of these patterns is called palatoscopy. It can be used in various fields such as sex determination, orthodontics and forensic odontology.

The gastric folds (or gastric rugae) are coiled sections of tissue that exist in the mucosal and submucosal layers of the stomach. They provide elasticity by allowing the stomach to expand when a bolus enters it.
What are Haustra?
The haustra refer to the small segmented pouches of bowel separated by the haustral folds. They are formed by circumferential contraction of the inner muscular layer of the colon. The outer longitudinal muscular layer is organized into three bands (taeniae coli) which run from the cecum to the rectum.
Which cells of the gastric pits secrete mucus?
(1) Mucoid cells secrete gastric mucus and are common to all types of gastric glands. Mucoid cells are the main cell type found in the gastric glands in the cardiac and pyloric areas of the stomach.
