Question

Which of the following appendages arise from the pro thoracic part of a cockroach?

• A. Second pair of wings
• B. First pair of legs
• C. First pair of wings and legs
• D. First pair of wings

Answer 1

Answer: (B)

First pair of legs

• The thorax of the cockroach is divided into three distinct segments: the prothorax, mesothorax, and metathorax.
  
• Each segment of the thorax bears a pair of walking legs. Thus, the first pair of legs arise from the prothorax.
• The first pair of wings arise from mesothorax and the second pair from metathorax.

So, the correct option is B.
