Question

Which part of Cockroach leg is attached to thorax ventrally?

• A. Trochanter
• B. Claw
• C. Femur
• D. Coxa

Answer 1

The correct option is D Coxa

The thorax in cockroach bears three pairs of walking legs, a pair in each thoracic segment. Each leg is formed of 5 podomeres. They are coxa, trochanter, femur, tibia and tarsus. Coxa is the basal stout portion of the leg, articulating with the ventral side of the thoracic segment. It is internally hollow and is filled with striated muscle fibres.

So, the correct answer is 'Coxa'.
