What is the function of the patella? The patella naturally increases the length of the quadriceps muscle moment/lever arm The patella causes the quadriceps to produce less muscle torque The patella helps the quadriceps produce more muscle FORCE The patella naturally decreases the length of the quadriceps muscle moment/lever arm

Step 1
The patella, or kneecap, is a small bone located in front of the knee joint. It is embedded within the tendon of the quadriceps muscle. Show more…

When you bend your knee, the quadriceps muscle is stretched. This increases the tension in the quadriceps tendon attached to your kneecap (the patella), which in turn increases the tension in the patella tendon that attaches your kneecap to your lower leg bone (the tibia). Simultaneously, the end of your upper leg bone (the femur) pushes outward on the patella. The figure shows the relationship between the quadriceps muscle, the patella, and the tibia.

When you bend your knee, the quadriceps muscle is stretched. This increases the tension in the quadriceps tendon attached to your kneecap (patella), which in turn increases the tension in the patella tendon that attaches your kneecap to your lower leg bone (tibia). Simultaneously, the end of your upper leg bone (femur) pushes outward on the patella. The figure shows how these parts of the knee joint are arranged (Figure 1).

The upper leg muscle (quadriceps) exerts a force of 1250 N, which is carried by a tendon over the kneecap (the patella) at the angles shown in Figure 9.37 . Find the direction and magnitude of the force exerted by the kneecap on the upper leg bone (the femur).
