### Step-by-Step Solution:

1. **Identify the Classification**: Cockroaches are classified as invertebrate insects. This means they do not have a backbone.

2. **Examine the Body Structure**: Cockroaches have three main body parts: the head, thorax, and abdomen. The thorax is particularly important for movement.
