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 located on the left side of the human body in the upper part of the abdominal cavity. It is a muscular organ and is part of the digestive tract. It communicates with the esophagus through the cardia and with the small intestine through the pyloric sphincter.
