The muscle found inside the alimentary canal is primarily smooth muscle. This type of muscle is involuntary and responsible for the peristaltic movements that propel food through the digestive tract. Smooth muscle contractions help in the mixing and digestion of food, facilitating movement along the gastrointestinal tract. In some areas, such as the esophagus and anal sphincter, there may also be skeletal muscle, which is under voluntary control.
