what is the functionality of tagmosis in arthropods?

Question

do not really know any help would be great

Answer 1

Tagmosis is the evolutionary process of fusing and modifying segments in metameric organisms such as arthropods to form tagmata. In insects, the body segments (somites or metameres) have become fused into three main tagmata: the head, thorax and abdomen. Segments making up each tagma can be either completely fused (e.g. the head capsule) or more loosely connected (e.g. the abdomen).
