Morphology

prothorax = thorax (semi-transparent) = pro + thorax

The form is a regular combination of 'pro-' (before/front) and 'thorax', but 'pro-' in this anatomical sense is specialized and may be unfamiliar to average learners.

Etymology

Prothorax is made of pro- meaning 'before' or 'in front' and thorax meaning 'chest'. So the prothorax is the insect's 'front chest', the part that holds the first pair of legs.
