The scorpions "head" is found in its cephalothorax. Being invertebraes, they contain no spinal cord or spinal comlumn; however, they do have nerves, nerve cords, and neurons- these function as connectors of the PNS, and the CNS, as well as the cephalothorax.
The central nervous system consists of a brain and ventral nerve cord. The brain is comprised of two large ganglia that surround the esophagus. One section of the brain interprets optical sensory and is the source of complex behaviors. The other part of the brain controls movement. |
A pair of nerve cords connect the two main ganglia, and this one object makes up the scorpion's brain.
Scorpions interpret vibrations through hairs that are deflected by air when it moves past them. There is one main nerve cord that runs down the length of the scorpion. Attached to this one cord are seven other ganglia, which may also control the scorpion's movement. |
