APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -In the stomach, the empty state is contracted and its mucosa and submucosa are released into detached folds called rugae. These rugae are also known as gastric folds or gastric rugae. When the stomach is distended with food, the rugae are ironed out and flat.

Detailed explanation-2: -Gastric rugae are the redundant folds of gastric mucosa that are most prominent when the stomach is collapsed. The reservoir and mixing functions of the stomach demand a thick, expansile, muscular vessel, which characterizes gastric morphology. Gastric mucosa is composed of columnar epithelium.

Detailed explanation-3: -The lining of the stomach at rest is thrown into thick, velvety folds called rugae. These contain microscopic invaginations, called gastric pits, that each open into four or five gastric glands.

Detailed explanation-4: -Mucosa (mucous membrane) is the innermost layer lining the lumen of the alimentary canal. Since it secretes mucus to lubricate the inner lining of the gut it is called mucosa . This layer forms irregular folds called rugae in the stomach.

Detailed explanation-5: -> Rugae-When there is an empty stomach, the lining that is present is thrown up as folds. These are termed as the Rugae.
