What are the 3 main body parts that all arthropods have?

Arthropod segments have also fused together into functional units called tagma. This process of segment fusion, or tagmosis, usually results in an arthropod body that consists of three major sections, a head, thorax, and abdomen. Sometimes the head and thorax are fused together into a cephalothorax.

Which arthropods have 4 pairs of legs?
