IPA: /prəʊˈθɔːrəsɪk/
KK: /proʊˈθɔrəsɪk/
Related to the front part of the thorax in certain insects, which is the segment just behind the head.
The prothoracic segment is crucial for the movement of the insect's forelegs.
Prothoracic → It is formed from "pro-" (meaning before) and "thorax" (from Greek "thorax", meaning chest or breast). The word "prothoracic" refers to something related to the thorax that is situated before or in front of the thorax.
Think of 'pro-' meaning 'before' and 'thorax' meaning 'chest' — so prothoracic refers to something located in front of the chest.
