Final answer:
The insertion site for the patella ligament is the tibial tuberosity, which is a prominent area on the anterior aspect of the tibia where the ligament attaches to facilitate knee extension. The correct option is c.
Step-by-step explanation:
The insertion site for the patella ligament is at the tibial tuberosity. This site is an elevated region located on the anterior surface of the tibia, close to its proximal end. The patella itself is a sesamoid bone within the tendon of the quadriceps femoris muscle, which is the large muscle on the front of the thigh.
The quadriceps muscle extends the leg at the knee joint, and the patella ligament plays a crucial role in supporting and stabilizing the knee by acting as both a part of the muscle-tendon complex and as a protective structure for the tendon by keeping it away from the femur.
The patella ligament originates at the base of the patella and then proceeds to the tibial tuberosity. It does so to facilitate the action of the quadriceps muscle in extending the knee. The tibial tuberosity offers an anchorage point for this extension, adding leverage that enables the quadriceps muscle to work more efficiently.
