Answer:
Tagmata.
Step-by-step explanation:
There are some characteristics that make arthropods unique animals. For example, their segmented bodies, jointed appendages, and strong exoskeletons. The arthropod's body is divided into three main regions called TAGMATA: The head, thorax, and abdomen are part of it. They are formed by groups of body segments that sometimes are fused together and others are linked by joint tissue. There are arthropods that have modified their appendages that have functions like feeding, being sensitive to the environment, walking, swimming and protecting against predators. A jointed appendage help arthropods to have greater flexibility and movement. The nervous system of arthropods is made up of two nerve cords coming from the ventral, or bottom, the interior surface of the body.
