In terms of Brodmann areas, the prefrontal cortex traditionally includes areas 8, 9, 10, 11, 44, 45, 46, and 47 (to complicate matters, not all of these areas are strictly granularâ44 is dysgranular, caudal 11 and orbital 47 are agranular).
A starfish's mouth is on the center of its bottom side. Its stomach  is directly behind the mouth after a short esophagus and extends a  bit down its five arms.
The stomach is an organ of digestion. It has a saclike shape and is located between the esophagus and the intestines. Almost every animal has a stomach. The human stomach is a muscular, elastic, pear-shaped bag, lying crosswise in the abdominal cavity beneath the diaphragm.
