INTRODUCTION

Arthropods are lower animals and their complexity is not profound as compare to the higher animals. As we move higher in phylum the complexity of organisms belonging to the phylum increase. 

Arthopod is derived from greek words  'Arthron' meaning joints and 'pous' meaning foot, the animals belonging to this phylum have this  characteristic  feature that is they have jointed appendages besides having exoskeleton made up of chitin and most importantly they are invertebrates ie they lack the vertebra in their skeleton.

On the other hand vertebrates have complex anatomy and their neural networks are more complex as compared to the arthropod. 

The movement we see in insects are very quick and abrupt while in vertebrates it is more coordinated and subtle. Innervation of neurons occurs both in the skeletal system of these organism but lets see the differences.
