The folds in the mucous membrane lining of the stomach are called?

Explanation:
In the stomach, the folds of the mucous membrane are called rugae. These mucosal folds allow the stomach to expand as it fills with food and liquids, and they become less prominent as the stomach stretches to its full size. This distinguishes them from similar-looking features in other parts of the digestive tract: plicae circulares are circular folds seen in the small intestine to boost surface area for absorption, while microvilli and villi are microscopic and finger-like projections on epithelial cells in the small intestine that also increase absorption, not folds of the stomach lining. So the term that matches the stomach’s folded lining is rugae.
