Detailed explanation-1: -In Arthropod animals the body consists of a head, thorax and abdomen. In Insects, head and thorax remain separate and are not fused together into Cephalothorax. These are characterised by an exoskeleton and joint appendages.

Detailed explanation-2: -The thorax is the midsection (tagma) of the hexapod body (insects and entognathans). It holds the head, legs, wings and abdomen. It is also called mesosoma or cephalothorax in other arthropods.

Detailed explanation-3: -Cephalothorax (or prosoma): The anterior (or front) major body segment, literally a fusion of the head and thorax. Pedicel: A narrow tube which connects the two major body segments, it carries the gut, blood supply, and ventral nerve. Abdomen (or opisthosoma): The posterior (or back) major body segment.

Detailed explanation-4: -Class Insecta is classified under the subphylum Hexapoda. It includes bees, ants, grasshoppers, and other insects. Their body has three segments called the head, thorax, and abdomen.

Detailed explanation-5: -The cephalothorax, also called prosoma in some groups, is a tagma of various arthropods, comprising the head and the thorax fused together, as distinct from the abdomen behind.
