Question

Which of the following represents X and Y in the figure given below?

• A. X- organ, Y - muscle
• B. X - muscle, Y - joint
• C. X - joint, Y - bone
• D. X - bone, Y - organ

Answer 1

The correct option is B X - muscle, Y - joint

The label 'X' is a muscle whereas the label 'Y' is a joint. Muscles move the joints by contraction and relaxation. On contraction, the muscles get shorter and stiff and on relaxation, they get longer and loosen up. A joint is a point where two bones are connected. It aids in the movement of the bones.
