The stomach is surrounded by parasympathetic (stimulant) and sympathetic (inhibitor) plexuses (networks of blood vessels and nerves in the anterior gastric, posterior, superior and inferior, celiac and myenteric), which regulate both the secretory activity of the stomach and the motor (motion) activity of its muscles. Because it is a distensible organ, it normally expands to hold about one litre of food. The stomach of a newborn human baby will only be able to retain about 30 millilitres. The maximum stomach volume in adults is between 2 and 4 litres. Sections
In classical anatomy the human stomach is divided into four sections, beginning at the cardia. The cardia is where the contents of the oesophagus empty into the stomach. The fundus (from Latin bottom) is formed in the upper curved part. The body is the main, central region of the stomach. The pylorus (from Greek gatekeeper) is the lower section of the stomach that empties contents into the duodenum.The cardia is defined as the region following the "z-line" of the gastroesophageal junction, the point at which the epithelium changes from stratified squamous to columnar. Near the cardia is the lower oesophageal sphincter. Research has shown that the cardia is not an anatomically distinct region of the stomach but a region of the oesophageal lining damaged by reflux. Anatomical proximity
The stomach bed refers to the structures upon which the  stomach rests in mammals.
