Phylum Arthropoda is the largest phylum of Animalia which includes insects. Arthropods have a very basic nervous system consisting of a brain located dorsally and a ganglionated longitudinal nerve cord on the ventral side. Many Nematodes are parasitic.
Describe the structure of the nervous system of arthropods Most insects have a simple central nervous system with a dorsal brain linked to a ventral nerve cord which is made up of ganglia that runs along the middle of the thorax and the abdomen. Each part of the CNS plays an important role in how the body functions and the three components of the CNS work together to take in information and control how the body responds. In this basic anatomy of a hexapod note that insects have a developed digestive system yellow a respiratory system blue a circulatory system red and a nervous system purple.

They have organ-system level of organization. Comparative studies on structure and development of the nervous system have contributed important arguments to this discussion. Nerves that supply cephalic sense organs.
However many arthropod activities are controlled at the. An arthropod is an invertebrate animal phylum Arthropoda and include the insects arachnids crustaceans and others. Central Nervous System Structure.
The innervation can attain quite a complexity but no consistent pattern has been found that holds true for all insects. The arthropod central nervous system consists of a dorsal ganglionic mass the brain lying above the stomodaeum anterior most part of the digestive system. It is the fused form of nerves.
