Final answer:
The knee joint includes three articulations: the femoropatellar joint, the medial tibiofemoral joint, and the lateral tibiofemoral joint. The femoropatellar joint is between the patella and the distal femur, allowing for patella gliding. The medial and lateral tibiofemoral joints enable knee flexion and extension. option 2 is answer
Step-by-step explanation:
The knee joint includes three articulations: the femoropatellar joint, the medial tibiofemoral joint, and the lateral tibiofemoral joint.
The femoropatellar joint is between the patella (kneecap) and the distal femur (thigh bone). It allows for the gliding of the patella during knee movements.
The medial tibiofemoral joint is located between the medial condyle of the tibia (shin bone) and the medial condyle of the femur. It allows for flexion and extension of the knee.
The lateral tibiofemoral joint is situated between the lateral condyle of the tibia and the lateral condyle of the femur. It also permits flexion and extension of the knee. option 2 is answer
