Rugae
Rugae
Rugae (pronounced: roo-jee) are anatomical structures found in various parts of the body. They are a series of ridges produced by folding of the wall of an organ. Most commonly, they are associated with the gastrointestinal tract, specifically the stomach and the palate.
Etymology
The term "rugae" is derived from the Latin word "ruga", which translates to "wrinkle" or "fold". This is a fitting description of the physical appearance of these structures.
Function
Rugae serve several important functions in the body. In the stomach, they allow for expansion and contraction to accommodate varying amounts of food. In the mouth, the palatal rugae help in manipulating food during chewing and also play a role in speech.
