Muscularis externa can be described as a muscular region which is present in vertebrates, especially in the stomach of the vertebrate organism. The muscularis externa provide movements like peristalsis and contractions after intervals. These muscles enable food to get churned and mixed with the digestive enzymes. There is a circular layer of muscles present in the muscularis externa which prevents moving of the food in the backward direction hence leading the food to move in the right direction.
