prothorax
anatomy
Quick Summary
The prothorax is the anterior segment of the thorax in insects. The thorax itself is the middle of the three major body divisions in insects, with each of its three parts typically bearing a pair of legs. The meso- and metathorax (the second and third segments) usually have wings. In insects like heteropterans, the pronotum is a prominent part of the thorax, located between the head and the wings. The term "prothoracic" relates to the prothorax.1234
