Does an insect have a head and the thorax and the abdomen?

We describe an insect's body as head, thorax and abdomen. That means something like "head, chest and belly".

In much the same way as humans, crocodiles, and dogs are built, the chest or "thorax" of an insect is between the belly and the head.

In fact, the Word "thorax" applies to the human body as well; we speak of thoracic surgery, the thoracic cavity, and thoracic vertebrae for example.
