Factor that helps regulate digestion Description special smooth muscle cells in the muscularis externa of digestive tract organs that contract in a rhythmic cycle when threshold is reached. a network of about 100 million neurons in the submucosa and muscularis externa layers of digestive tract organs that controls the secretion of GI epithelial cells and controls GI tract motility. sympathetic and parasympathetic nerve fibers that modify the activity of the enteric nervous system, alter the level of GI hormones and act directly on the smooth muscle and glands in the digestive system.
