Large mucosal folds formed when the stomach is empty are called ____

A	the rugae
B	the fundus
C	the muscularis layer
D	the pyloric sphincter

Explanation:

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.

Detailed explanation-3: -> Rugae-When there is an empty stomach, the lining that is present is thrown up as folds. These are termed as the Rugae.

Detailed explanation-4: -In the empty state, the stomach is contracted and its mucosa and submucosa are thrown up into distinct folds called rugae; when distended with food, the rugae are “ironed out” and flat.
