Question

In the following diagram of a leg of Cockroach parts have been indicated by alphabets. Choose the answer in which these alphabets have been correctly matched with the parts which they indicate

• A. a = coxa, b = tibia, c = tarsus, d = femur, e = trochanter
• B. a = coxa, b = femur, c = trochanter, d = tarsus, e = tibia
• C. a = coxa, b = tarsus, c = femur, d = tibia, e = trochanter
• D. a = coxa, b = trochanter, c = femur, d = tibia, e = tarsus

Answer 1

Answer: (D)

a = coxa, b = trochanter, c = femur, d = tibia, e = tarsus

In Cockroach, there are three pairs of thoracic legs on the ventral side. Each leg is five jointed or segmented. The upper portion of the leg, called the coxa, attaches the leg to the thorax. The other parts of the leg approximate parts of a human leg: The trochanter acts like a knee and lets the roach bend its leg. The femur and tibia resemble thigh and shin bones.

So the correct answer is 'a = coxa, b = trochanter, c = femur, d = tibia, e = tarsus'.
