The Thorax
The skeleton of the thorax or chest (Figs. 112, 113, 114) is an osseo-cartilaginous cage, containing and protecting the principal organs of respiration and circulation.
thorax -- In insects, the second body region, between the head and thorax. It is the region where the legs and wings are attached.

thorax
[Gk. breastplate]
(1) In vertebrates, that portion of the trunk containing the heart and lungs. (2) In crustaceans and insects, the fused, leg-bearing segments between head and abdomen.

Classification of Arthropods
Due to their great diversity of appendages, lifestyles, and other features, arthropods are usually separated into several subphylums.
Ultrabithorax (Ubx) is an example of a "selector gene".
Selector genes are genes that regulate (turning on or off) the expression of other genes. Thus selector genes act as "master switches" in development.
They have something called a cephalothorax that is actually several sections of exoskeleton fused together. They have also developed a shield for their head. An insect head is sitting out there and could be bitten off.

The hexapoda have the head, thorax, and abdomen differentiated, and are mostly winged.
These targets were the Bithorax complex (BX-C) and the Antennapedia complex (ANT-C). Both complexes have been nearly completely sequenced and submitted to Genbank by the LBL directed genomic sequencing group.
Unlike the other phyla, they have a well-differentiated head, thorax and abdomen.
