The stomach has three layers of muscle, known as the muscularis externa, which consist of an outer longitudinal layer, a middle circular layer, and an inner oblique layer. These layers work together to facilitate the mixing and churning of food, aiding in digestion. The coordinated contractions of these muscles help propel the food through the stomach and into the small intestine. This unique arrangement allows for effective mechanical digestion.

What are the three sheets of muscle in the stomach muscularis externa?

The muscularis externa of the stomach consists of three distinct sheets of muscle: the outer longitudinal layer, the middle circular layer, and the inner oblique layer. The outer longitudinal layer runs along the length of the stomach, while the middle circular layer encircles the stomach, helping to mix and propel the contents. The inner oblique layer is unique to the stomach and aids in the mechanical breakdown of food. Together, these layers facilitate the stomach's complex movements essential for digestion.
