MEDICAL PHYSIOLOGY

Detailed explanation-1: -The smooth muscle portion of the esophagus has myenteric plexus similar to the small intestine. However, peristalsis in the smooth muscle portion of the esophagus is very different than the intestine; the esophagus, but not intestine, can produce peristalsis at will (primary peristalsis).

Detailed explanation-2: -The muscle movements of peristalsis are often described as wave-like because they contract and relax in a continuous pattern to move food forward. They involve both the circular muscles that ring the tubes of your digestive tract and also longitudinal muscles that span the walls of the tubes.

Detailed explanation-3: -Key Points. Esophageal peristalsis results from sequential contraction of circular muscle, which serves to push the ingested food bolus toward the stomach. Esophageal longitudinal muscle may also play a role in peristalsis.

Detailed explanation-4: -Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.

Detailed explanation-5: -Smooth Muscle Tissue It plays an important role in the regulation of flow in such tissues for example aiding the movement of food through the digestive system via peristalsis. Smooth muscle is non-striated, although it contains the same myofilaments they are just organized differently, and involuntary.
