11.   Which of these describes bending the knee joint to bring the lower-leg and upper-leg bones closer together?

What are your choices?

To determine which term describes bending the knee joint to bring the lower-leg and upper-leg bones closer together, we need to understand the anatomy and movement of the knee joint.

The knee joint is a hinge joint that connects the femur (thigh bone) to the tibia (shin bone). It also involves the patella (kneecap) and fibula (a smaller bone located next to the tibia).

The movement of bending the knee joint to bring the lower-leg and upper-leg bones closer together is known as flexion. Flexion occurs when the angle between the bones decreases, such as when you bring your heel towards your buttocks.

Therefore, the correct answer is flexion.
