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.
Starfish have five or more (in some species) arms that radiate outward from a central body disc. The upper-side of their body can be smooth, bumpy or spiny. The mouth of starfish is located under the central body disc and tube feet line the bottom side of the arms.The tube feet enable the starfish to move using a hydraulic system, also known as a water vascular system. Most starfish are bottom feeders.Starfish are often brightly colored animals.he mouth of starfish is located under the central body disc and tube feet line the bottom side of the arms.
