middle body region of an arthropod consisting of three fused main segments that may bear legs and wings

in arthropods, posterior body region of an arthropod that contains fused segments, digestive structures, reproductive organs, and bears additional legs: in humans, part of body that is between the diaphram and pelvis

in arthropods, the structure formed from the thorax region fused with the head

in arthropods, a structure such as a leg or an antenna that grows and extends from the outside body covering.

in arthropods, the periodic shedding of the protective exoskeleton so their bodies can continue to grow

in most arthropods, one of the pair of mouthparts adapted for biting and chewing food

in most terrestrial arthropods, one of a system of tubes that branch into smaller tubules and carry oxygen throughout the body
