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

The correct option is D A = Coxa, B = Trochanter, C = Femur, D = Tibia, E = Tarsus

Leg of cockroach has five parts. Jointed legs are present in Cockroach. The upper portion of the leg, called the coxa, attaches the leg to the thorax. The other parts of the leg are :

• The trochanter acts like a knee and lets the roach bend its leg.
• The femur and tibia resemble thigh and shin bones.
• The segmented tarsus acts like an ankle and foot. The hook-like tarsus also helps roaches climb walls and walk upside down on ceilings.

A = Coxa, B = Trochanter, C = Femur, D = Tibia, E = Tarsus
