With this diagram, Punch (1841) pokes fun at phrenology by classifying the four great divisions of the stomach.  Amazingly, the spoof is perfectly accurate!  The "Sustaining Faculties" at the lower belly take cognizance of those staple foods which are essential to the sustenance of animal life.  The "Affections" govern the more delicate appetites gratified by the contemplation of finer meals to come.  The "Superior Sentiments" at the center "direct the stomach to the investigation of sauces, French cookery, and other abstruse subjects."  The "Intellectual Taste" at the top of the belly is "the faculty of reasoning and reflecting upon the abstract qualities of olives, the Italian salads, of comparing Stilton with Gruyère cheese, and tracing the relation between turtle-punch and headache."
