Local reflexes and parasympathetic stimulation increase the production of intestinal juice. The intestinal juice is composed of water, electrolytes, mucus, and enzymes. It is produced by the glands and crypts in the intestinal wall. Local reflexes and parasympathetic stimulation increase the production of intestinal juice, whereas sympathetic stimulation inhibits it. The pancreas produces pancreatic juice, which is different from intestinal juice. Motilin stimulates intestinal motility, not the production of intestinal juice. The cephalic phase of gastric secretion is related to the stimulation of gastric juice production, not intestinal juice.
