Summary Introduction
To define: The terms tergum, sternum, telson, protopod, exopod, endopod, epipod, endite, and exite.
Introduction: Arthropods are the most abundant invertebrates found on earth. Most of them are insects. They have a segmented body and have appendages. They have exoskeleton present on their body which is used by them for their protection.
