Detailed explanation-1: -Arthropods are bilaterally symmetrical protostomes with strongly segmented bodies. Segmentation affects both external and internal structure. Some segments are fused to form specialized body regions called tagmata; these include the head, thorax and abdomen, and the process and condition of fusion is called tagmosis.

Detailed explanation-2: -Tagmata are the specific sections (i.e. Head, Thorax, Abdomen), which may vary from species to species. Some important features of arthropods are their open circulatory system, molting, coelomate, protostome and the fact that they live in almost all habitats on earth.

Detailed explanation-3: -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.

Detailed explanation-4: -The three insect tagma are: Head. Thorax. Abdomen.

Detailed explanation-5: -tag·ma. ˈtagmə plural tagmata.-mətə : a compound body section of an arthropod resulting from embryonic fusion of two or more somites (as the cephalothorax of a spider) or consisting of two or more distinguishable segments (as the thorax of an insect)
