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.
Your stomach is located at the end of your esophagus and is the terminus for swallowed food and drink. The stomach receives chewed food and continues to mechanically and chemically break it down into smaller pieces, creating more surface area for your small intestine to absorb nutrients.
