APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -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-2: -A series of normal coordinated, rhythmic muscle contractions, that occurs automatically to move food through the digestive tract is called peristalsis.

Detailed explanation-3: -Peristalsis is the automatic wave-like movement of the muscles that line your gastrointestinal tract. Peristalsis moves food through your digestive system, beginning in your throat when you swallow and continuing through your esophagus, stomach and intestines while you digest.

Detailed explanation-4: -The muscularis layer of the GI tract is also known as muscularis externa. This layer is further divided into two muscular layers: inner circular layer and outer longitudinal layer. The muscularis layer generates peristaltic movement and segmental contractions within the digestive tract.

Detailed explanation-5: -Mechanical digestion in the stomach occurs via peristaltic contractions of the smooth muscle from the fundus towards the contracted pylorus, termed propulsion.
