Explanation:
Detailed explanation-1: -Extrinsic autonomic influence modulates activity – parasympathetic activity tends to increase peristalsis and sympathetic activity to inhibit it.
Detailed explanation-2: -The sympathetic nervous system moves blood away to other organs, interferes with the regular contractions of the muscles along the digestive tract and decreases secretions needed for proper digestion.
Detailed explanation-3: -When the stomach is filled, peristaltic waves are diminished. The presence of fat in a meal can completely stop these movements for a short period until it is diluted with gastric juices or removed from the stomach.
